Step 1: Assess legacy systems and regulatory requirements
Before you move anything to the cloud, you need a clear picture of what you’re actually working with. This means examining your current systems in detail—what they do, how they perform, where the pain points live, and how they connect to everything else. It’s not glamorous work, but this assessment determines whether your cloud migration succeeds or stumbles.
Start by documenting your existing core systems, policy administration platforms, claims engines, billing software, and any custom-built applications that handle critical functions. For each system, record when it was built, what programming languages it uses, how many people depend on it daily, and what data it processes. You’ll also want to understand integration points: which systems talk to each other, how data flows between them, and whether those connections are robust or fragile. This inventory becomes your foundation for determining what can migrate relatively smoothly and what requires significant rework. Legacy systems often contain business logic that nobody fully understands anymore because the original developers have moved on, which makes this documentation step even more vital.
Regulatory compliance sits alongside technical assessment with equal importance. European property and casualty insurers face specific requirements around data residency, solvency capital requirements, GDPR obligations, and sector-specific insurance regulations that vary by country. You need to understand which regulations apply to your operations and which cloud environments meet those requirements. This isn’t just about location of data centres—it includes audit trails, encryption standards, access controls, and change management procedures. Modernising core systems requires careful attention to these regulatory constraints, which often push insurers toward incremental approaches rather than big-bang replacements.
Mapping these technical and regulatory requirements side by side reveals your actual constraints. Some legacy systems may seem essential but actually hold you back from meeting newer compliance standards. Others might be fully compliant but run so inefficiently that cloud migration offers immediate operational benefits. You might discover that certain data flows violate current regulations and need restructuring regardless of cloud plans. This assessment phase typically takes 4 to 8 weeks depending on system complexity, but rushing through it means making poor decisions later that cost significantly more to fix.
Here is a summary of the types of legacy systems and their cloud migration implications:
| Legacy System Type |
Common Challenges |
Migration Considerations |
| Policy Administration |
Complex business logic |
Requires deep documentation before migration |
| Claims Engine |
High transaction volumes |
Needs robust integration and data validation |
| Billing Software |
Sensitive financial data |
Prioritise regulatory compliance and encryption |
| Custom-Built Applications |
Unknown dependencies |
Demands thorough assessment and refactoring need |
Document performance metrics too: response times, uptime percentages, error rates, and support costs. Cloud platforms often provide better performance and reliability metrics, so understanding your baseline helps you quantify improvement potential. A slow legacy claims system handling 50,000 transactions weekly represents a genuine business problem that executives understand when you show them concrete numbers rather than vague complaints.
Pro tip: Involve your compliance and risk teams in this assessment from day one rather than bringing them in after technical decisions are made. They’ll identify regulatory blockers early, preventing expensive rework and ensuring your migration plan aligns with oversight requirements from the start.
Step 2: Develop a migration roadmap and stakeholder alignment
Once you understand what you’re working with, you need a clear plan for moving forward and buy-in from the people who’ll make it happen. A migration roadmap without stakeholder alignment sits gathering dust on a shelf. Equally, stakeholder enthusiasm without a concrete roadmap leads to confusion and wasted effort. This step brings those two elements together.
Start by bringing together your key stakeholders across IT, business operations, compliance, finance, and any lines of business affected by the migration. This isn’t a one-time meeting but the beginning of ongoing collaboration. Each group sees cloud migration through a different lens: IT focuses on technical feasibility and system performance, finance worries about costs and timelines, compliance thinks about regulatory exposure, and business leaders want faster innovation and better customer experiences. Your roadmap needs to address all these concerns, which is why developing effective cloud migration strategy requires close collaboration between IT and business stakeholders from the outset. Prioritise getting these voices in the room early rather than announcing decisions after technical teams have made them.
Structure your roadmap using the 7R approach: rehost, replatform, refactor, repurchase, retire, retain, and relocate. This framework helps you categorise each application or system according to what actually makes sense for it. Some legacy systems might work perfectly well on cloud infrastructure with minimal changes (rehost). Others need updating to run efficiently in cloud environments (replatform or refactor). Some are so outdated that replacing them with modern cloud native solutions makes financial sense (repurchase). A few might genuinely work better staying on premises for now (retain). Using this structured approach prevents the trap of trying to move everything the same way, which wastes money and creates unnecessary complexity.
The following table outlines the 7R approach and its business impact on cloud migration:
| 7R Migration Strategy |
Description |
Typical Business Impact |
| Rehost |
Lift-and-shift to cloud |
Quick wins, low risk, limited optimisation |

Risk mitigation, deferred transformation |
| Relocate |
Move systems with minimal modifications |
Containerisation opportunities, flexibility |
Once you’ve categorised your systems, build out phased waves rather than attempting everything simultaneously. Most European insurers move incrementally, balancing cost and risk management. Wave one might include non-critical systems that generate quick wins and build confidence. Wave two could tackle more complex policy administration platforms. Wave three addresses the most business critical claims systems. This phased approach lets you learn from early implementations, adjust your processes, and build internal expertise before tackling the hardest migrations. Each wave should have clear success metrics: cost savings achieved, performance improvements measured, compliance validations completed, and team readiness for the next phase.
Alignment extends beyond the initial planning phase. Strategic approaches for aligning teams within insurance require clear communication channels, centralised project tracking, and real-time collaboration throughout the entire migration. Use consistent governance structures where decisions flow clearly, responsibilities are explicit, and status updates reach stakeholders regularly. When someone from claims operations understands why a policy administration decision was made and how it affects their timeline, they become an advocate rather than a blocker. Transparency builds momentum.
Document your roadmap clearly but resist making it too rigid. Market conditions change, regulatory requirements shift, technology evolves, and unforeseen technical challenges emerge during implementation. Build in review points every quarter where you assess progress, validate assumptions, and adjust the plan if necessary. A roadmap that adapts based on real learning outperforms a fixed plan that ignores new information.
Pro tip: Designate a single executive sponsor from the business side and ensure they have decision-making authority to resolve trade-offs between departments. This prevents endless debates about priorities and ensures your roadmap moves forward rather than stalling at conflict points.
Step 3: Prepare data and applications for secure transition
Moving systems to the cloud requires meticulous preparation. You cannot simply copy everything across and hope for the best. Data quality, application readiness, security posture, and compliance validation all need attention before the actual migration begins. This preparation phase prevents costly problems during and after the move.
Begin with a comprehensive data audit. Legacy insurance systems often carry years of accumulated technical debt: duplicate records, inconsistent formats, obsolete fields, and data quality issues nobody noticed because they worked around them. During migration, these problems surface immediately. Identify duplicate customer records across your policy administration and claims systems, standardise date formats and field mappings, remove obsolete data fields that serve no purpose, and validate critical data against your regulatory requirements. For claims systems, this means verifying that injury descriptions, liability assessments, and settlement amounts follow consistent patterns. For policy administration, ensure policyholder contact information, coverage details, and premium calculations are accurate and complete. This cleaning process typically consumes 15 to 25 percent of your total preparation timeline but prevents far more painful cleanup work later.
Application preparation runs parallel to data work. Review each application or system scheduled for migration and document its current dependencies, integrations, performance characteristics, and security configurations. Does your policy administration system connect to external rating engines? Does your claims system feed data to financial reporting tools? Identify every integration point because cloud environments may handle these connections differently. Test these integrations thoroughly in a staging environment before moving to production. Also assess your application security posture now: are you encrypting sensitive data in transit and at rest? Are access controls enforced properly? Is your audit logging comprehensive? Cloud platforms provide security capabilities, but they work only when properly configured. Ensure your applications meet modern security standards rather than assuming the cloud infrastructure will solve security gaps.
Data migration itself deserves careful planning. Zero downtime migration approaches protect business continuity during the transition, ensuring your claims handlers, underwriters, and customer service teams face minimal disruption. Develop a detailed migration plan that specifies exactly which data moves in which sequence, validation checks at each step, rollback procedures if something goes wrong, and communication protocols for notifying stakeholders of progress. Test your migration process end-to-end in a staging environment using production data volumes and realistic timelines. Nothing reveals problems faster than practising the actual migration before you do it for real. Document everything discovered during testing and update your procedures accordingly.
Security validation requires special attention. Verify that encrypted data remains encrypted throughout the migration process. Confirm that access controls apply correctly in the new cloud environment. Validate that your compliance requirements around data residency and audit trails are met. Run penetration testing or security assessments on your new cloud setup before moving live. Insurance systems handle sensitive information about customers and claims, making security breaches catastrophically expensive. The investment in thorough security validation before migration far exceeds the cost of discovering security gaps afterwards.
Communicate transparently with your operational teams throughout preparation. Claims handlers need to understand how their workflow changes. Underwriters need to know what policy administration looks like in the new system. Customer service teams need training on any interface changes. Involve these teams in user acceptance testing rather than surprising them with changes after migration completes. Their feedback identifies usability problems and helps refine your transition plan.
Pro tip: Create a detailed rollback plan before you migrate anything, documenting exactly how you would revert to the legacy system if critical problems emerge during the transition. Having this safety net documented gives your team confidence and ensures you can make that decision quickly if necessary rather than being locked into a failing migration.
Step 4: Execute migration and enable system integration
This is where preparation meets action. You have assessed your systems, developed your roadmap, and prepared your data. Now you coordinate the actual move to the cloud and ensure all your systems work together seamlessly in their new environment. Execution requires discipline, clear communication, and rapid problem-solving when unexpected issues emerge.
Begin by implementing a change freeze period before your migration cutover window. This means no new deployments, configuration changes, or system updates across any of the systems involved in the migration. A change freeze typically starts 48 to 72 hours before cutover and prevents last-minute modifications that could complicate migration or introduce new problems. Notify all stakeholders clearly about this freeze so nobody attempts changes during this critical period. Your IT operations team, business stakeholders, and any external integration partners all need to understand that the freeze is non-negotiable. During this window, run final validation checks: verify data synchronisation between old and new environments, confirm integration connections are ready, test failover procedures, and ensure monitoring and alert systems are configured. Structured execution guidance for cloud migrations emphasises the importance of stakeholder preparation, finalising environments, and conducting careful migration cutovers to minimise downtime and ensure seamless integration.
Your cutover window requires a coordinated approach. Start by migrating non-critical systems first, even if only for validation purposes. Once you confirm that a system operates correctly in the cloud environment and its integrations function properly, you gain confidence for tackling more critical systems. For a large property and casualty insurer, this might mean moving rating engines first, then policy administration, then claims systems. Each cutover involves a precise sequence: stop processing on the old system, validate that no new data is in flight, migrate the final data increment, start the new cloud system, validate data integrity, reconnect all integrations, and test end-to-end workflows. Document every step and who is responsible for each one. Ambiguity during cutover creates chaos.
Integration testing becomes your safety net. Before switching any system to production, verify that it communicates correctly with systems already running in the cloud and those still on legacy infrastructure during any hybrid period. If your policy administration system needs to send data to your rating engine and billing system, test those connections thoroughly. If your claims system retrieves customer data from policy administration and writes settlement information to financial systems, validate those workflows work as expected. Conduct this testing in an environment that mirrors production as closely as possible, using realistic data volumes and actual system configurations.
Monitoring requires heightened attention during and immediately after cutover. Set up comprehensive logging and alerting on all systems, especially those newly migrated. Watch for performance degradation, data synchronisation delays, integration failures, or security alerts. Assign a dedicated incident response team to address problems immediately rather than waiting for normal business hours. Response time matters immensely during cutover. If a critical issue emerges at 2am on a Sunday, having a team ready to respond prevents small problems becoming catastrophic failures. Partnering with experienced technology vendors and system integrators reduces risk considerably, particularly for complex insurance platforms where integration challenges emerge regularly.
Communicate progress relentlessly. Your executive sponsor needs updates every few hours during cutover, showing which systems have migrated successfully and which face challenges. Your operational teams need to know when their systems will be available and how long any downtime will last. Your customers ultimately depend on your systems working reliably, so consider communicating status updates to them if cutover spans hours when they would normally access your services. Transparency builds confidence even when issues occur.
Validate that business processes work end-to-end once all systems are running in the cloud. Can your underwriters rate policies correctly? Can your claims handlers process claims from initial report through settlement? Can your customer service team access all the information they need? Run your documented test scenarios and watch for anything that works differently than before. Some differences might be improvements, others might represent genuine problems requiring quick fixes.
Pro tip: Maintain your legacy systems in a stable state for at least two weeks after successful cloud cutover before decommissioning them, giving yourself a safety window to address any unexpected post-migration issues without the pressure of a full rollback.
Step 5: Verify cloud deployment and ensure compliance
Your systems are now running in the cloud, but the work is far from finished. You need to verify that everything operates correctly, meets your regulatory obligations, and performs as expected. This verification phase determines whether your migration succeeded or created new problems requiring urgent attention.
Begin by running comprehensive validation tests across all migrated systems. Test your policy administration platform by creating test policies, retrieving them, modifying coverage, and generating documents. Test your claims system by submitting test claims, assigning them, creating reserves, and processing payments. Test your rating engine by running quotes across various risk profiles and coverage combinations. Test your billing system by generating invoices, processing payments, and producing financial reports. These functional tests confirm that systems work as designed in their new environment. Performance testing matters equally. Compare response times, database query speeds, report generation times, and batch processing durations against your pre-migration baseline. Cloud environments often perform better than legacy systems, but sometimes unexpected performance issues emerge due to network configurations, database indexing, or application tuning. Identify these problems now rather than discovering them when underwriters complain about slow quote systems or claims handlers struggle with sluggish workflows.
Compliance verification requires systematic attention to regulatory requirements. Your data must reside in the correct geographical region according to regulations like GDPR and local data residency rules. Verify that your cloud provider’s data centre locations match your compliance obligations. Confirm that encryption is active on all sensitive data at rest and in transit. Validate that your access controls restrict who can view policyholder information, claims details, and financial data. Run an audit trail verification confirming that all system changes, data modifications, and user access are logged properly. Managing regulatory compliance in cloud migrations requires understanding data sovereignty, regulatory frameworks, and implementing region-specific controls to maintain compliance whilst enabling cloud scalability. Document every control you’ve implemented and maintain evidence showing compliance with each applicable regulation. Regulators expect this documentation during examinations.
Integration validation confirms that systems communicate correctly in their new cloud environment. Does your policy administration system send policy data to your billing system and receive premium payment confirmations? Does your rating engine receive risk information from your underwriting system and return accurate quotes? Does your claims system retrieve policyholder information from policy administration and forward settlement data to financial reporting? Test each integration end-to-end with realistic data volumes. Some integrations work fine with 100 test records but fail under production load. Discover these issues during validation rather than when your systems are live.
Security validation goes beyond basic encryption and access controls. Conduct vulnerability scanning on your cloud infrastructure to identify any exposed configurations or missing security patches. Run penetration testing or engage external security professionals to attempt unauthorised access. This adversarial testing reveals weaknesses before attackers find them. Verify that your backup systems function correctly and can restore data if needed. Test your disaster recovery procedures by simulating a major outage and confirming you can failover to backup systems. Insurance companies cannot afford extended downtime, so these recovery capabilities matter tremendously. Effective compliance during cloud migrations requires classifying data by sensitivity, selecting compliant cloud providers, implementing strong encryption and access controls, and establishing governance policies that sustain regulatory adherence post-migration.
Validate that your monitoring and alerting systems function correctly. Confirm that you receive notifications when systems experience performance degradation, security alerts trigger, or data synchronisation fails. Test your incident response procedures by simulating a critical alert and verifying your team responds appropriately. Operational monitoring becomes your early warning system for problems, so ensure it’s configured comprehensively.
Documentation captures everything validated. Create a compliance certificate listing each regulation applicable to your operations and evidence showing compliance. Document all security controls implemented and their testing results. Record performance metrics achieved and compare them against targets. This documentation becomes essential for internal governance, regulatory examinations, and future audits.
Pro tip: Schedule your compliance verification with your internal audit team and external regulators if possible, allowing them to observe your validation processes and confirm they meet regulatory expectations rather than discovering gaps later.
