2 min readAn original planning guide. Use the linked primary documentation for platform details and the supported procedure for your environment.
Inventory recipients and senders
List mailboxes, aliases, groups, forwarding rules, website forms, and services sending as the domain. Include shared-team workflows.
Plan data and access
Define how historical mail and folders will be copied and checked. Confirm user access and recovery methods for the new service.
Sequence service changes
Use each provider's current instructions for DNS and authentication. Decide how to handle overlap and messages arriving during the move.
Test both directions
Send controlled messages into and out of representative accounts. Check aliases, website mail, and actual recipient placement as well as send status.
Worked scenario
See the plan in practice.
A website form uses a sending service independent of staff mailboxes. Include it even if the mailbox migration itself is complete.
