I just finished this. Only took about 2 weeks for 8 hosts ;) I had
to do this:<br>
<br>
3.5 -> 3.6<br>
<br>
- upgrade engine to 3.6 <br>
- create a new cluster with CL 3.6<br>
- for each host:<br>
- maintenance<br>
- reinstall to el7 + RPMs (yay for puppet)<br>
- add to new 3.6 cluster<br>
- activate<br>
- migrate some machines to new cluster (no way back!)<br>
- elevate CL of old (empty) cluster to 3.6<br>
- migrate everything back for each host<br>
<br>
3.6 -> 4.0<br>
- for each host:<br>
- maintenance<br>
- upgrade RPMS to 4.0<br>
- activate<br>
- elevate CL to 4.0 (can be done with running VMs)<br>
