How to Migrate a Cloud Application With a Legacy Batch Processing Dependency

A migrated application may rely on an older batch processor that uses local files, fixed schedules, or unsupported libraries. The web tier can work while overnight processing fails or produces incomplete results.

What to check

Inventory batch schedules, input and output locations, runtime versions, service accounts, dependencies, and downstream consumers. Compare a representative run in the target environment and reconcile output with the source.

Recommended next step

Migrate or replace the batch dependency as part of the plan, with a controlled overlap to prevent double processing. Confirm data completeness and recovery behavior before disabling the original job.
