I have a client with a server on CentOS-4 and I'm looking to upgrade to latest horde/imp/etc. clearly php 4.3.9-xx is not up to the task but I see that upgrades for php & mysql are in CentOS-Plus I see that CentOS-4 projects to get security updates until 3/2012 which probably is the usefulness of the hardware itself. So my questions... - Will CentOS-Plus maintain the php/mysql packages until then? - The upgrade to mysql-5...do I have to nuke the db and reload from backup or is there a possibility that the upgrade and subsequent restart of mysql will update the database stuff itself (of course I'm gonna do a complete dump of mysql data before attempting)?
