Splitting a server

[fconil]

Hi, I have a server currently serving domain A and domain B, with a ratio of 10%/90%. Server is running zimbra NE 6, and is on a private lan, NAT-ed behind the same address for mail.domainA and mail.domainB

For some reason, company B wants their own server, and I thought of this process:

Rename mail server from mail.A.com to mail.B.com using zmsetservername

Create "new" mail.a.com

Migrate the mailboxes from former server A to new server A using a ZCS to ZCS backup script/migration tool. (or even a plain old Zdesktop export in the worst case scenario)

Is it completely stupid?
Should I just create a mail.B.com and migrate all the mailboxes for domain B there? there is quite a number of those, and some of them are well over 20G each, hence my initial approach.)

Personally I'd create a new server with the new name and move the mailboxes over, even though it may be a lot. It will save any possible ldap issues with server name changes. I try to avoid Changing deter names as much as possible.

If you do change server names, don't forget about Ssh and ssl keys also.

Fair enough.
I guess after that all that will be left will be the domain forward.
