Data-center migration Gantt timeline
A data-center migration timeline organizes discovery, planning, target-platform preparation, application work and cutover into one dependency plan. The pilot migration waits for both the platform and the refactored applications, and the cutover follows the pilot. Hypercare makes the support period after the change explicit. This diagram is helpful for a steering discussion because it shows what must be true before each transition. It does not replace a technical runbook or a recovery plan.
Open it in the AI editor with a prompt pre-filled — keep what works, change what doesn't.
Scenario
An IT team plans a migration with a pilot before production cutover.
Key decisions
- Inventory first: Scope systems before planning.
- Coordinate streams: Platform preparation and application refactoring both feed the pilot.
- Use a milestone: Cutover follows a completed pilot migration.
When to reuse this
Use to explain the dependency structure of a migration before building a detailed runbook.
