- Stage schema migrations with rehearsal environments and rollback options.
Readiness checkpoints
- Async workloads reach parity benchmarks with legacy workers.
- Observability dashboards monitor CPU, memory, and I/O across environments.
- Cutover plans rehearsed with dry runs and clear rollback procedures.
