Hi, For the backup, add the --scope=all argument as follows: engine-backup --scope=all --mode=backup --file=/root/backup It will backup many more things than only the database. Restore the backup on the new host, when it finishes you need to run engine-setup to fill any gaps from the backup and the version you just installed. It may run changing nothing but is required, so your commands should be: engine-backup --mode=restore --file=backup --log=backup_restore.log engine-setup ()s Marcos -----Original Message----- From: narutospinal(a)gmail.com <narutospinal(a)gmail.com&gt; Sent: Monday, October 21, 2024 5:03 PM To: users(a)ovirt.org Subject: [External] : [ovirt-users] Migration of oVirt Engine and Hosts from CentOS 8 to CentOS 9 Dear, I would like help with the following question: I need to migrate my oVirt Engine and oVirt Hosts from CentOS 8 to CentOS 9. My plan is to back up the database using the engine-backup command. For example: engine-backup --mode=backup --file=db_backup My next step will be to install the oVirt Engine on CentOS 9 and restore the backup. For example: engine-backup --mode=restore --file=db_backup --log=backup_restore.log --change-db-credentials --db-host=didi-lap --db-user=engine --db-password=your_password --db-name=engine Finally, I will add a new oVirt Host with CentOS 9 and migrate the virtual machines. Are there any considerations I should be aware of? Could you please guide me? _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://urldefense.com/v3/__https://www.ovirt.org/privacy-policy.html__;!... oVirt Code of Conduct: https://urldefense.com/v3/__https://www.ovirt.org/community/about/communi...
