Please define backup store? Are you going to create a script or something to copy the store? In that case, why not backup the most critical things like ldap, etc.

If you use that, then the migration should be relatively simple.
The software needs to be upgraded, but all the data will remain the same.
Basically, backup your /opt/zimbra
Install RHEL64 on your new machine
Install RHEL64-ZCS on your new 64bit machine. None of the settings will matter, but install it anyway.
You MUST, MUST, MUST install your current version of ZCS. For example, if you're running 4.0, then you will need to install the 4.0 64 bit on your server. Now isn't the time to upgrade zcs. You should do that later.
su - zimbra
su - root
rm -rf /opt/zimbra
rsync -avr /old/zimbra /opt
chown -R zimbra:zimbra /opt/zimbra*
Good luck, and if you need anything, just hollar.
