Currently running with a managed VPS, centOS 5.10. Want to upgrade to centOS 6.
So in reading this http://wiki.centos.org/HowTos/MigrationGuide/MigratingFiveToSix
Upgrades are not supported by *yum*, I get that, and essentially what I have been told by the webhost is that in order to upgrade a new webeserver should be built on centOS 6 and then install services over top of that, in my case, essentials, whm, cpanel etc, have added openvpn server, teamspeak. Guess what I am asking is to those that have done such a migration, what are the issues you have run into, compatibility, configuration, mysql config, php, apache. What do you recommend, what are things to avoid. What should I expect?
As I would rely on the webhost to perform this work for me, helps if I have a little more insight from those here that have done this and are running sites with xf. Have 3 websites running on the server currently, 2 xenforo, and one built with strictly html, just a playground.

I see a few people here have a lot of experience with this, so you input is greatly appreciated.
