Hi,
After the previous debacle with PHP and MySQL it has been decided that we think about an upgrade from CentOS 3 to 5, since that would solve our problem, if successful. I tried finding information on how to best attempt this, but thanks to a plethora of contradictory information my head is now spinning with a few rpm (rounds per minute).
The situation is as follows: Remote box at our host who offers CentOS 3 as the most up-to-date OS, unless you pay them an unholy amount of money for RHEL or Windows licences. Popping in a CD for an upgrade does not work for us. We can and will have the OS restored to a clean post-install state prior to updating. I have little intimate knowledge with CentOS, RPMs or yum, but general good UNIX experience. I know "live" yum migrations are greatly discouraged, but it seems to work for people.
The most detailed instructions I seemed to be able to find are here: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=382 Can anybody confirm this to work, is there anything else that's implied but not spelled out? Another, differing approach seems to be this: http:// levine.sscnet.ucla.edu/general/software/tc1000/rmredhat.htm Any ideas about it?
Any hints, or rather detailed steps, would be greatly appreciated. Chrs, Dav
