I have several systems which are at client locations, which are still on version 5.0. Now it's summertime, and they're schools, the time has arrived for upgrades and enhancements (spamassassin for one).
The documentation seems to indicate that I should be able to perform a straight 5.0 => 5.6 upgrade, and of course, I will be doing backups, I'd just like to know if anyone has had any problems doing this?
Thanks, Nick
