I have to do a migration of around a dozen email inboxes from my current host, and some are small only taking a few hours at most, but a couple are very large (~20gb) and the migration for these could several weeks.
The problem is that some of my email addresses need to use MX Route’s mail server, while others on the same domain will still need to use Site 5’s mailserver (so I don’t have donwtime/missed emails during the migration etc). Is it possible and if yes, how do we configure the DNS to do that?
To note, all these email addresses are cPanel email accounts. I am wondering if MX Route has a way where I could send you the individual email files from cpanel, and MxRoute could directly put those files on the server?
Thanks
