I'm facing a situation with some of my Zimbra servers.

As time goes by I try to 'concentrate' all my Zimbra installs on my main ESXi server for safety reasons, since it is located in a Datacenter with reduntant power supply, ups, lots of storage etc..

Some of my first customers, however, still have their mail server 'at home' and is beginning to be a problem, both in management and safety, so I decided to migrate them all to a new VM in the ESXi machine.

The problem is: HOW?!

Imapsync or zxztozmig (zimbra's CLI utility for migration) are off the list, because I need to migrate Shares, Mountpoints, Tags, Docs and all the other elements of the accounts, not just mail or calendar/addressbooks. In some cases, there are domains on the server that are not to be migrated (internal domains for special applications).

Any ideas? I tried kinda everything.. LVM snapshots, rsync, ldap+store export.. Every solution I tried has some kind of fault that makes it not viable for me..

Thank you for your Help,

JP

You didn't specify what versions of Zimbra you were using (commercial or open source), however, you can just move the /opt/zimbra directory in a cold migration via scp or rsync.

Also, Zimbra gives comprehensive instructions here: http://wiki.zimbra.com/wiki/Moving_ZCS_to_New_Server

I did that some months ago, but I had no luck on getting shares/etc. What we did was to use the backup cli to export the accounts and import them back on the new servers.

I don't know if it fits to your case (or if you managed to solve the problem in other ways), but I recently tried a tool called ZeXtras Migration Tool to migrate one of the domains I manage to an other Zimbra server (see http://wiki.zextras.com/wiki/ZeXtras_Migration_Tool_Guide for more info).. Worked pretty good, it's worth a try!
