Cloud Migration Without Downtime
Strategies for migrating mission-critical systems while maintaining business continuity.
Verion Solutions9 min read
Migration patterns
Use strangler-fig patterns to migrate incrementally: route new workloads to cloud-native services while legacy systems continue operating. Dual-write and reconciliation phases ensure data integrity during transition.
Risk mitigation
Mitigate risk with rollback plans, parallel runs, and phased user migration. Never migrate everything at once - validate each phase with real production traffic subsets.
Post-migration optimization
After migration, optimize for cloud-native capabilities: auto-scaling, managed services, and cost observability. The goal is not just relocation but improved resilience and velocity.
