I need a guide on how to migrate Mail, Calendar and Contact Data from a ZCS 7.1.2 Network Edition on CentOS5 to ZCS 7.2.0 Netowork Edition on CentOS 6.
I know about the guide Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki , but this does not seem to be of a big help to me, as the old and the new server don't have the same name, don't have the same IP address and I don't know all the configuration details from the old server.
Situation is as follows:
Old Server servers domain1.com.
New Server has maindomain.com and should start to hold other domains for other people.
So the new server is already there and now I would like to import the Mail, Calendar and Contact data from the old Server with domain1.com.
I found HOT Backup and HOT Restore - Zimbra :: Wiki which looks pretty cool, but I'm not sure if it will work for Network Edition.
Any help is appreciated.
