When I tried to upgrade using upgrade-6.12.65-23.sh I got 2 (minor) errors.
- ./upgrade-6.12.65-23.sh: line 204: Install: command not found . I suppose you forgot the # at that line
- No package GeoIP available. I am not sure if this an serious error or not (Its from the command yum -y install mysql-log-rotate multitail GeoIP perl-Geo-IP)
