Changing default domain

[spokz]

Hello.

I have to change my main domain from, let's say, "A" to "B".

During installation I always used domain "A" - server and Zimbra are configured for it. For example, in Server Settings (Zimbra Administration Console) there is the Name of Service Server pointing to "hostname.A" domain.

I don't know exactly what variables in Debian and Zimbra configuration I need to change to provide 100% functionality after this migration.
What I know/guess is the need of:
- DNS reconfiguration
- /etc/hosts file edition
- changes in Zimbra Administration Console (regarding to new domain)

Please help me to specify what files and configuration have to be changed to have this done right.

Thanks, Michal.
