Replace your legacy system in phases, not all at once.
Big-bang migrations fail because they try to replace everything simultaneously. We decompose your legacy system into modules and replace them one at a time -- each phase is self-contained, tested, and reversible. Your operation never stops.
Big-Bang Migrations Are the #1 Way to Destroy an Operation
Service Scope
Break your legacy system into logical modules -- order management, inventory, pricing, financials, reporting. Define boundaries, dependencies, and migration sequence.
Prioritize which modules to migrate first based on business value, technical risk, and dependency chains. Quick wins first to build confidence.
Build integration between migrated and not-yet-migrated modules. Both systems work together during the transition period -- no functionality gaps.
Every phase has a tested rollback plan. If a migrated module doesn\'t perform, you revert to the legacy version while issues are resolved.
Defined acceptance criteria for each phase -- data accuracy, performance benchmarks, and business process verification before proceeding.
Continuous risk assessment as each phase progresses. Issues identified early are resolved before they compound in later phases.
Engagement Process
Analyze the legacy system and decompose into migratable modules. Map dependencies between modules and external systems.
Define the migration sequence -- which module first, second, third. Build the detailed plan with timelines, resource requirements, and success criteria.
Migrate the first module with full parallel running and validation. Prove the approach works before committing to subsequent phases.
Execute subsequent phases, incorporating lessons learned. Each phase gets faster as patterns are established and integration bridges are proven.
Once all modules are migrated and validated, decommission the legacy system with data archival and compliance documentation.
Frequently Asked Questions
Every engagement starts with an assessment.
