Question regarding server migration

[deltatango]

Hi all,

I want to migrate our Zimbra server to a new machine.The migration docs tell me I should give the new server the same LDAP password as the old one has. But where can I find the old server's LDAP password?
Is it in /opt/zimbra/conf/slapd.conf?

Can I just copy the entire conf/ directory over to the new server, reboot it and then restoring the user data from the backup?

Which instructions are you reading for the move? The usual one recommended is this: Moving ZCS to Another Server » Zimbra :: Blog

I was referring to this one:
Network Edition Disaster Recovery - Zimbra :: Wiki

The link mentioned by you moves the server by rsync-ing the data. This would be easy and there's not much to do wrong.

But I don't want to do this because I want a clean, fresh installation for the new server.

The old one underwent already may be a dozen updates during the last more than 24 months and each of the updates left a plethora of old files and directories in the Zimbra tree. I dare not to delete them as I cannot be sure they are really unused. So to get rid of the obsolete stuff I want to do a clean install by restoring the server from backup.

And I'm not entirely sure whether I will run into some architecture problems (32 vs 64Bit) with rsync-ing: the old server is a Mac Mini under 10.4 Workstation, while the new one is an XServe under 10.4 server.

Third reason is to really do a Disaster recovery and to be sure
a) how it works and
b) the backups are actually sufficient for a complete restore.
c) to have a proven step-by-step checklist documented

I do this for every kind of server or appliance - I want to know my stuff - but I didn't had the time yet to do this with the mail server.
