Migrating an application to a new platform with minimal code changes to improve operations and scalability.
Replatforming is the migration of an application to a different platform with minimal code changes to improve operational characteristics or scalability. The method targets platform-level optimizations (e.g., containers, PaaS, or cloud services) rather than full re-engineering. It typically reduces migration risk and time compared with a complete rewrite.
Total duration from planning to production cutover.
Number of incidents per time after migration.
Comparison of ongoing costs before and after replatforming.
API was migrated into containers without functional change and integrated into existing CI/CD pipeline.
Batch jobs were moved to managed PaaS services, reducing administrative effort.
Parts of the shop migrated to a scalable container environment, better handling peak loads.
