I am looking for a way to migrate the complete configuration of a mail server from one server (let's call it A) to another (called B). The DNS entries of the servers are different and I would like to keep it that way if possible. The whole purpose of this exercise is to set up a test bed for updating server A to 4.5.4 so as to verify that data loss will not occur, while at the same time verifying that we can have something of an easily restored backup if necessary.
Installation on server A is ZCS 4.5.1 on Intel OSXS 10.4.9.
Installation on server B is ZCS 4.5.1 on PPC OSX 10.4.9.
I did a full export from server A with the following command (or at least I think I did):
zmbackup -f -z -a all -t /opt/zimbra/backup/full/
I then transferred the contents of the full directory to the same directory on the other server (incidentally, I thought that the -z switch was supposed to zip the files...?). I then ran this command:
zmrestore -a all -sys -rf -c -t /opt/zimbra/backup/full
The restore did not seem to display any fatal errors, but it was not able to import the current email accounts (which are formatted like this: firstname.lastname@example.org).
Since then the services will not start on server B. I attempted to uninstall Zimbra on server B using ./install-mac.sh -u but a subsequent reinstall errored out. I am not overly concerned with this part at the moment, but I am getting a little worried about being able to get a zimbra installation back up and running in the case of server failure.
Any help would very much be appreciated.
