So, I'm going for the upgrade from 4.5.11 to 5.0.11 this weekend and I'm feeling more apprehensive about this upgrade than any of the others... I really don't know why. I'm just looking for any tips you can offer, or any success stories going this route...
I'm pretty confident that I've followed the 5.0.11 upgrade notes, I'm on the latest version of the OS, I don't have any LDAP replicas to worry about etc.
So this is what I'm going to do
1) Take a full backup using zmbackup
2) Stop Zimbra and copy /opt/zimbra to another location (This will take about 8 hours)
3) Then run the install.sh
I know I've done before so many times, but I don't think I've upgraded in such a huge jump before... Will anyone sooth my worried brow?
