[Solved] Install CheckMK on a new Host with CheckMK 2.3 (RHEL9) and import backup from CheckMK 2.2 (RHEL7) possible?

We’d like to create a new monitoring host with RHEL9, CheckMK 2.3 and then import a Backup of a RHEL7 Host with CheckMK 2.2.
Is this even possible?

Thanks
Tony

You can only restore a backup to the exact version of Checkmk from when it was taken.

You need to install Checkmk 2.2 in RHEL9 and then upgrade the site to 2.3.
