[ovirt-users] migrate from stand alone on FC19 to hosted OK to use CentOS 7?

I am trying to migrate my old ovirt install which started out at 3.3 standalone engine on FC19 to a hosted engine. I want to use CentOS , however, the postgresql version on 6.5 is old (8.4.20) and I am unable to get a clean restore. The version on FC 19 is 9.2.8, it looks like EL 7 has 9.2.7 (I am hoping the difference in the minor rev will not bite me). I was wondering if there are any issues using EL 7 to host the engine? I know I had seen some reports of issues with 3.5 on EL7 as hosts but was not sure if the engine had any gotchas. Thanks, Alastair
