 Migrating large mail accounts might take a lot of time. For example migration of cca. 1.5GB mail account took almost 3 days!!! But this will depend on how many attachments there are in the account, number of emails etc. Migrating large mail accounts might take a lot of time.

 +===== NOTES: =====

 +  * Enable IMAP on both the source and destination account
 +  * "Folder size limits" in Gmail Settings must be set to "Do not limit the number of messages in an IMAP folder (default)". This is the default.
 +  * when migrating from multiple domains you must add MX records for them
 +  * on the migration assistant screen, when you are done with emails from one domain exit the Migration Assistant (**More > Exit migration**) then start the migration again for the users with new domains. If you don't do this you'll get an error "Failed estimating mailbox size".
 +  * if you are transferring the same domain, make a temporary domain with mx records on the source account and move user's email to this domain. Then remove the domain from source account and add it to the destination account
 +  * domain can only be removed once the user's email and email aliases are removed (**check each user > User information > Alternate email addresses (email alias)**). Remove the domain you are transferring from here.
