Migrating from RHEL 6.2 KVM to RHEV 3.0

I currently have a RHEL KVM Host running VMs from a local disk (LVMs on a seperate partition from the OS).

I would like to use RHEV-M to manage my existing VMs. Is this wise? Also, is there anything I should look out for. I'm trying to figure out my approach. I would like to keep RHEL but I don't want to run RHEV in an unsupported configuration. 

I want to assume that I can add the RHEL boxes to RHEV-M and on boot all the VMs would come up in RHEV-M.

Any advise or input would be greatly appreciated!
