Hi all,
I am trying to upgrade an oVirt installation (3.6.7.5-1.el6) to 4.0.
My datacenters and clusters have 3.5 compatibility settings.
I just finished this. Only took about 2 weeks for 8 hosts ;) I had to do
this:
3.5 -> 3.6
- upgrade engine to 3.6
- create a new cluster with CL 3.6
- for each host:
- maintenance
- reinstall to el7 + RPMs (yay for puppet)
- add to new 3.6 cluster
- activate
- migrate some machines to new cluster (no way back!)
- elevate CL of old (empty) cluster to 3.6
- migrate everything back for each host
3.6 -> 4.0
- for each host:
- maintenance
- upgrade RPMS to 4.0
- activate
- elevate CL to 4.0 (can be done with running VMs)
