Question CentOS2Alma conversion: Your expectations and experience?

[ArmReu]

Hi everyone! I will sooner or later have to convert two existing servers from Cent OS 7.9.2009 to a current OS so upgrading to AlmaLinux 8 with this tool makes sense.

My question: Has anyone current experiences if the upgrade runs seamless with the tools current release. I see last answers to this post are over 3 month old, that's why I'm asking...

Kindest regards from Germany!

We did not dare to use it. We choose a Plesk to Plesk migration for dozens of servers.

Yeah, that was my other thought too. OS upgrading a live server feels a bit "thrilly" for sure.

So you had good experience with the migrator? Even when migrating from an old/different OS to a newer one?

Yeah, the Plesk Migration Manager works great.

Make sure to do some 'dry runs' with all the data to see what issues might turn up and to figure out how long a migration takes.

For some servers we did 10 of these dry runs and while keeping an eye on the extended logs found and fixed all sort of "migration bugs" along the way.
Sometimes reducing migration time with 50%. For example: al sorts of migration tests are available within PMM. They are great but not necessary when you've done multiple dry runs. So after enough dry runs, do the live migration without the tests and save loads of time.
