Unable to find a decent tutorial on this and the dovecot wiki doesn't seem to specify much other than the command line parameters for doveadm sync.
I need to move emails from a hosting provider to a new server I've set-up (time-bound on this before the old hosting provider charges for another year). The new server has been set-up with postfix and dovecot. These have been configured in the following manner.
Dovecot does authentication Dovecot file holds users and passwords 2 x domains set-up (example.com and example2.com)
This set-up works for inbound and outbound for example.com and example2.com.
Old hosting provider with domain oldexample.com holds several mailboxes to be migrated. While I can access the server via SSH it is extremely locked down so no root access or even access to install anything. If I've understood correctly I can use dovecot on the new email server to pull the accounts using the dsync utility via IMAP.
The questions I have (before I start) are
- Do I need to create the users from oldexample.com on the new server before I attempt the sync?
- Do I need to add the domain oldexample.com to the new server config before or after I attempt the sync?
- When should the MX records etc for oldexample.com be updated - presumably after the sync?
Any help appreciated or if there is a tutorial out there with this information (and any other relvant info) that I've missed please point me in that direction.
