Questions about transferring accounts and email.

[johnbuddha]

I'm about to transfer some cPanel/WHM accounts from one dedicated server to another and was curious about what happens to email during the transfer.

My assumption, and based on a previous transfer, it seems like any mail being sent to the account being transferred on the old server is 'suspended' or something to that effect.

Can anyone confirm this or point me to any documentation on that process?

Secondly, after transferring accounts I've noticed a large in the size of the accounts according to cPanel on both servers. After they've been transferred they seem to take a lot less space on the new server. Everything -seems- alright, and my first inclination is to think perhaps they're logs that are being left behind, however if anyone could shed more light I'd really appreciate it.

Thanks,
John

The mail will still go to the old server unless you cluster the servers together and that way the dns will change over right away.

As for the space difference, this may be a miscalculation in the quota. You should run a manual check to see the disk space size.

In a nutshell:

several days before the move, drop the ttl on the domains to something small, like 5 minutes.

stop mail services
edit the dns zones on the old server so that the new IP addresses are shown.
transfer the account
restart mail services

by having the new IP address information on the old server, any queries that come to the old one will point to the new one and mail will get delivered there.

There are a couple of threads here somewhere that detail the whole thing... holler if you can't find them.
