I upgraded from 4.0.2 to 4.5.6 on Saturday 19th January and today I ran out of disk space. I am on RHEL5.
I noticed that there is a folder in /opt/zimbra/backup called
drwxr-xr-x 3 root root 4096 Jan 19 12:12 4.5.6_GA
It contains one folder:
drwxr-xr-x 7 root root 4096 Jan 19 12:06 4.0.2_GA-5.3
(created the same time I did the upgrade).
It is 12G and I was wondering if it is safe to delete it? (I am copying it somewhere else first).
I can't find anything in the upgrade notes about it. The notes do say to perform backups - which I did (copied the entire opt/zimbra folder to another place on disk.) Is this another backup that the upgrade script performs?
