[ovirt-users] appliance upgrade 4.0 to 4.1

[Artyom Lukianov]

The correct way to upgrade appliance from 4.0 to 4.1

   1. Enable GlobalMaintenance
   2. Add the 4.1 repositories to the appliance
   3. Update the relevant packages
   4. Run # engine-setup
   5. Disable GlobalMaintenance
   6. Change cluster and datacenter compatibility version

The --upgrade-appliance command was added just for the purpose to make an
easier pass from 3.6 to 4.0, all other scenarios not supported.
Best Regards
