OpenNebula on SLES12 SP 1

Hi , I’ve got a question. Right now I have the Sunstone installed on a SLES 11 SP3 , and the kvm nodes are running over SLES 11 SP3 too. But now I would like to upgrade Sunstone to SLES 12 SP1 , without migrating… but my question is, should I move the KVM nodes to SLES 12 SP 1 too?
I have opennebula compiled from source, and the idea is to continue doing so… would you recommend this ?
