In practice
For mailboxes it means copying mail and switching MX records. For senders it means moving to a new sending platform, which usually brings new sending IPs and a new reputation to build gradually.
Verification and sending
A migration is a good moment to clean up. Verify the list before moving it so you do not carry dead addresses to a new platform.
