Basically, you can manually do what the tool is supposed to do:<br>
1. Make sure state is clean and stable (no running/pending storage actions,<br>
no VMs in the middle of migration etc), all clusters are compat level 3.6, etc.<br>
2. Move to global maintenance<br>
3. backup the engine using engine-backup and keep the backup elsewhere<br>
4. Reinstall engine vm with el7 and 4.0 engine (the tool will use the engine<br>
appliance, you might too but not sure how exactly).<br>
5. Restore the backup and run engine-setup.<br>
6. If all looks ok, leave global maintenance.<br>
<br>
If you manually keep a full backup of the engine vm before step 4,<br>
you might be able to restore this backup if there are problems.<br>
Doing this in the provided tool is currently the main blocking issue<br>
for it. Hopefully will be provided in 4.0.1.<br>
<br>
Best,<br>
