Mainframe Modernization Best Practices
- 1Run a test migration on a non-production copy before the actual cutover
- 2Use AWS Schema Conversion Tool (SCT) for heterogeneous database migrations
- 3Enable DMS CloudWatch metrics — monitor CDCLatencySource and CDCLatencyTarget
- 4Validate migrated data with checksums or row counts after migration completes
- 5Keep the source database running in read-only mode until validation is confirmed
