Evaluating the transition
Before you decommission any redundant infrastructure post transition, a rigorous evaluation should be performed to ensure that everything is operating as expected.
- Test workloads in target deployment.
- Test user access and processes, ensure run-books are updated.
- Ensure that data is synchronized.
- When parallel infrastructure is used, begin a gradual cut-over by allocating a percentage of traffic to new deployment if possible.
- Scale up to support full workload.
- Complete cut-over and run for burn in period.
- Decommission any redundant infrastructure.
