Question
Plesk prepared a CLI script that in place converts Centos 7 to AlmaLinux 8. Is it possible to convert further to AlmaLinux 9?
Answer
The script is based on the Alma Linux ELevate project, which leans heavily on the LEAPP Project created for in-place upgrades of RedHat-based systems.
Since the Elevate engine does not support direct conversion to RHEL 9 like OSes (AlmaLinux 9, RHEL 9, RockyLinux 9), the conversion will be possible only from Plesk on CentOS 7 to AlmaLinux 8 and further to AlmaLinux 9.
Plesk developers will consider implementing an upgrade path CentOS 7 -> Almalinux 8 -> Almalinux 9 in the future. However, currently, we are concentrating on the CentOS 7 -> AlmaLinux 8 upgrade path.
