	We are not supporting anything :)

Yes we have to support upgrades on RHEL6. I would suggest to not 
explicitly test CentOS unless there is direct report that it differ from 
RHEL6 - i.e. that something is broken on Centos while it work on RHEL.

I would like to have keep at least one Fedora version in common in 
future. And threat this upgrade as exception.
And upgrade from Katello 1.2 to 1.3 support using backup/restore. And 
try to promise that in future we will do our best to have one version in 
common.
