Right now we use foss 7.0 on sles 10. We are getting ready to upgrade the /opt array with bigger disks and a new os, sles 11. The plan, right now is to format all arrays and install sles 11, install zimbra and later install bigger disks. My question is this, obliviously we want to keep all users email. What is the best way to do this so when sles 11 and zimbra 7.x.x is installed I can copy all users email back to the new zimbra install? We do have zimbra backed up using backup exec.
