Hello. If you want to use an installation file of a previous version you need to install
the package ovirt-engine-appliance-4.4-xxxx.rpm. You can use the command "yum install
https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/x86_64/ovirt-engine-app...
to do this.
You can go to the link to see all possible package options:
"https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/x86_64"
Keep in mind - this can only help with deployment problems. The final version of the
installation will still be the last one.
