Data-Center Migration Gantt Timeline

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.

需求

“Create a data-center migration timeline with inventory, migration planning, target-platform preparation, application refactoring, a pilot migration, cutover, and hypercare.”

接著試試Add a rollback rehearsal before cutover.Change hypercare to 10 days.

這張圖裡有什麼

看懂背後的決策。

01Inventory first

Scope systems before planning.

02Coordinate streams

Platform preparation and application refactoring both feed the pilot.

03Use a milestone

Cutover follows a completed pilot migration.

Use to explain the dependency structure of a migration before building a detailed runbook.

常見問題

Why include a pilot migration?

A pilot provides a controlled point to validate the migration before production cutover.

What is hypercare?

It is the focused support period immediately after a major change.

Can platform and application work overlap?

Yes. They are separate streams that can run in parallel after migration planning.
