Hi,

What is the best way to migrate a working zimbra instalation from x86 to x86_64 without loosing data nor settings ? Anyone with experiences/tricks to share ?

TIA

Don't do it?

Quite honestly, 64bit with Zimbra is pretty dicey unless you are running RHEL, or maybe CentOS. Theoretically you can copy the dynamic portions of the data over(the openldap store, mysql databases, zimbra configuration, store directories) and everything will be fine. I did it once that way and it was a little dicey.

What platform are you on right now?

I'm running it on top of Centos, as a xen VM. i would like to have all my stuff xen-aware (x86_64) so that's why i was/am contemplating it.

Here is a nice trick then. Xen can run a 64 bit kernel (under FC6) with a 32 bit userspace. (This is what I use for my primary Zimbra instance). The only caveat is that you do have to use setarch i386 for the install, but outside of that it works like a champ.
