Hello!
Trying to upgrade old 4.3 installation to 4.4 using this documentation:
https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_the_Manager_...
On the target engine service host got this error during restore operation:
Start of engine-backup with mode 'restore'
scope: all
archive file: backup.bck
log file: /var/log/ovirt-engine-backup/ovirt-engine-restore-20230224162609.log
Preparing to restore:
- Unpacking file 'backup.bck'
Restoring:
- Files
------------------------------------------------------------------------------
Please note:
Operating system is different from the one used during backup.
Current operating system: redhat8
Operating system at backup: redhat7
Apache httpd configuration will not be restored.
You will be asked about it on the next engine-setup run.

Provisioning PostgreSQL users/databases:

- user 'engine', database 'engine_history'
FATAL: Existing database 'engine_history' or user 'engine' found and
temporary ones created - Please clean up everything and try again
One more log is here:

Can you, please, help and provide some information how this can be fixed ?

Hello,
Did you do a clean install first and run the engine-install command already ?
Then you need to run the engine-cleanup now. Restore the database again. And afterwards
run engine-setup

What do you mean - run the engine-install ? Install required packages ? Yes they
installed.
I followed an upgrade documentation.
This is a clean OS install with required packages. No engine-setup was run yet.
BTW, you cannot run engine-cleanup after that failure.
The error is:

Anyone ? We really need to upgrade this old 4.3 installation.
There are a lot of VMs and huge VM disks there, so we cannot just migrate them to a new
fresh 4.4/4.5 environment using export/import or any other ways. All we can do is to
upgrade existing 4.3 install step by step.
Please help. Can provide all necessary additional logs if required.

Hello,
This is how I did it just recently. I have an centos 7 with a standalone
ovirt engine and a couple off nodes with vm's running on them.
I used this document as a guide.
https://www.ovirt.org/documentation/upgrade_guide/index.html
Make sure your environment is update to the latest 4.3
"engine-upgrade-check", "dnf update ovirt\*setup\" and then run
"engine-setup" and also " yum update --nobest"
On the 4.3 engine you need to stop the engine "systemctl stop ovirt-engine"
and even disable it "systemctl disable ovirt-engine"
Take the backup "engine-backup --scope-all --mode=backup --file=backup.bck
--log=backup.log"
Install a new minimal centos 8 stream, update it to the latest and greatest
and then add the repository "dnf -y install
https://resources.ovirt.org/pub/yum-repo/ovirt-release4.4.rpm";.
Then run "dnf module -y enable javapackages-tools pki-deps postgresql:12
mod_auth_openidc:2.3 nodejs:14" and "dnf distro-sync --nobest"
If you are using SSO on the oldenvironment you need to run this "dnf
install ovirt-extenstion-aaa-ldap ovirt-engine-extention-aaa-misc"
Install the packages "dnf install -y ovirt-engine"
Then copy over the backup and restore them "engine-backup --mode=restore
--file=backup.bck --provision-all-database"
Now run the command "engine-setup"
And that's it. make sure the ovirt-eninge on the new server is running
"systemctl status ovirt-engine" and start it if it isn't "sysemctl
enable
--now ovirt-engine"
Now you should see everything again but still need to upgrate the nodes.
Kind regards.
