Rename primary domain name in multi domain setup possible?

[Florian Beckmann]

Hi all,

I'm running Kolab 16.0.1 (on ubuntu ) with a multi-domain setup and would like 
to move everything to a new primary domain.

Is there a feasible way to rename the primary domain within kolab ?
What steps would be required (like renaming domain name in (which?) config 
files, ldap, mail folders, etc)?

Thanks.

cheers
Florian
