</span>The answer sort of depends on what you want. Do you want no downtime on your<br>
VMs or is downtime acceptable. Also are you running hosted engine or not?<br>
<br>
This is the basic plan which can be adjusted based on what your needs are:<br>
<br>
1. Update engine from 3.5 to 3.6 (if hosted engine might be trickier, not sure<br>
haven't played with hosted engine).<br>
2. Create a new 3.6 cluster.<br>
3. Put 1 host in maintenance (which will migrate the VMs to the other hosts).<br>
4. Remove the host from the DC.<br>
5. Install C7.2 on the host<br>
6. Add that host to the new 3.6 cluster.<br>
7. Optional (you can cross cluster live migrate some VMs from 6 to 7 (just not<br>
the other way around, so once the VM is moved its stuck in the new cluster).<br>
8. Go to 3 until all hosts are moved.<br>
9. Your 3.5 cluster should now be empty, and can be removed.<br>
10. Upgrade your DC to 3.6 (Can't upgrade if any lower clusters exist).<br>
<br>
If you can have downtime, then just shut down the VMs running on the host in<br>
step 3 before putting it in maintenance. Once the host is moved to the new<br>
cluster you can start the VMs.<br>
