Hi,
I am trying to update my old 4.5.5 system to the latest one, right now with no luck: I am writing to share some experience and hopefully to be pointed to the correct process.
My system runs entirely on centos8, version is 4.5.5-1.el8, engine is on a vm hosted on vmware, no self hosted engine.
The idea is to install a new engine vm, with almalinux10, import the backup taken from the old engine, and restore the system. After that I would upgrade all the hosts, one at a time.
I tried today the first time, unsuccesfully. Here are all the steps:
1. take the almalinux10 vm, install the ovirt software with these commands:
dnf copr enable -y ovirt/ovirt-master-snapshot rhel-10-x86_64 Why would you use the daily builds? Use the stable 4.5.7 release! dnf install -y ovirt-release-master epel-release dnf install -y ovirt-engine
Operation ended succesfully
2. import the backup taken from current 4.5.5 engine:
engine-backup --mode=restore --scope=all --file=/backup.tar.gz --log=/tmp/restore.log --restore-permissions
Operation ended successfully
3. Run engine-setup, here is the output (removed fqdn for privacy):

The log provided is so verbose that I can't spot the possible problem. I wonder, anyway, if this procedure is correct or whether I should do something different. For example I noticed that I am not asked to configure keycloak, since in the current production system I have freeipa. Without logs it's hard to spot the issue :) When its an install without Keycloak it does NOT ask to upgrade to Keycloak by default, see https://github.com/oVirt/ovirt-engine-keycloak/blob/master/keycloak_usage.md
Thanks for the possible help,
Andrea
