update from CentOS 5.x to CentOS 6.x is at best a crapshoot. Skilled admins should be able to fix whatever needs fixing. Less than skilled admins will find it takes less time to backup and re-install. As for switching to Ubuntu... I have switched my latest installs from RHEL/CentOS to Ubuntu. Primarily because I felt I couldn't rely upon timely releases/updates. Let me assure you though that nothing is perfect with any distribution and while some packages might be newer/more readily available on one distribution than the other, there are certainly other packages that are newer/better vice versa. ffmpeg on CentOS/RHEL 5.x is a bit behind (CentOS/RHEL 5 is way behind). zoneminder is just perl scripts so it doesn't make that much of a difference if it is RPM packaged or just tarball install CentOS/RHEL has a much larger window of support for a specific version than Ubuntu so claiming that Ubuntu has a 3 year window as an advantage suggests that you don't understand the RHEL/CentOS support windows at all.
