You should have the credentials to access the mailboxes to be migrated. You should have the rights and the capability to reset the passwords on the source in order to access the mailboxes OR should be able to delegate the access.
If the source server is hosted at your own premises, you have provisioned sufficient Internet bandwidth to transfer the mailbox data.
The source email service provider should allow large emails downloaded via IMAP/API without any throttling.
