A planned move of mail into Google Workspace or Microsoft 365.
Inventory, a cutover window, and a check that mail arrives where it should. Files, chat history, and other systems are included only when the scope lists them.
In a typical scope
- Mailbox inventory
- A scheduled cutover
- A check after the move
- Rollback notes before the cutover
Timing depends on mailbox size, access, and the source system. A migration is not an instant switch.
