System migration depends on the strategy you choose, whether it's a lift-and-shift or an upgrade approach. The planning process will differ in both cases due to the distinct nature of each migration type. A lift-and-shift involves moving systems as-is, while an upgrade requires adapting or enhancing the system during the migration, impacting timelines, resource allocation, and overall execution.

System migrations are like planning a space mission—every detail counts. I always start with a detailed migration plan that covers every aspect: timelines, dependencies, and risk management. Testing is my second lifeline—extensive pre-launch tests in a sandbox environment help me catch issues before they become disasters. Finally, stakeholder communication is critical. Keeping everyone—from devs to execs—updated ensures we're all on the same page, minimizing surprises. That way, when it's go-time, the migration is as smooth as a rocket launch with no unexpected turbulence.

One thing I have found helpful is keeping stakeholders informed and proper planning for migration and rollback strategy will lead to seamless migration.
