So - we want to change the OS platform that we run Zimbra on from RedHat 4 (32 bit) to Ubuntu LTS (64 bit) releases (or failing that to Centos). We think we have the right steps in mind, but wanted to double check with the folks here to make sure we don't have any ID10T moments:
1) shutdown current RH running zimbra instance.
1.1) Copy all of /opt/zimbra to new server
1.2) Copy all of /zimbra[x] datastore file systems over to new server (keeping the same file system structures (i.e. don't combine FS/etc.))
2) install zimbra Ubuntu LTS edition on new server
3) startup new Ubuntu based coolness
I know this sounds awfully silly to ask, but we are nervous.
Is this all the right steps? Anything we missed?
Thanks for the help and sanity check...
