And in any case this can be your friend for dependencies in updating
datacenters/cluster to 3.6:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Upgrade_Guide/chap-Post-Upgrade_Tasks.html

For their general concepts (in 3.6):
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Administration_Guide/chap-Data_Centers.html
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Administration_Guide/chap-Clusters.html

HIH,
