[BlueOnyx:25191] Re: Switch to Almalinux for existing CentOS installation?

[Dirk Estenfeld]

Hello Michael,

I am in principle also for the variant 1.
Because if it is not 98% sure that the process runs independently without any problems, but if it is 10% or more likely that problems occur, then that would be a problem if dozens of servers get a problem at the same time. You don't want to do the support (neither do I for our customers 😊 ).

Therefore +1 for variant 1 + sufficient hints that it is now possible. Perhaps in addition a troubleshoot page on which the most known problems and their solutions are listed.

best regards,
Dirk

Fully understandable.

I've done quite a bit of testing of the
https://github.com/AlmaLinux/almalinux-deploy script and I'm getting encouraging results.

However, my concern is how we want to deploy this. Because it's not entirely without risks. Two options:

1.) I provide an RPM that will be automatically installed via YUM. It contains the conversion script and possibly a page integrated into the GUI that informs people to run the script manually and explanations of why and how.

2.) RPM gets installed automatically via YUM. *After* the YUM update and during the next Active Monitor run a one-time-script automatically runs the conversion script. No user-input required.

Either way: There are chances that stuff breaks.

If we go option #1, some people might miss the deadline. But those that do the manual conversion with the provided tool will be able to see what is/was going on during the upgrade and have a chance to do it on their own terms.

Option #2 means everyone that auto-updates via YUM will get it during the next YUM run and the conversion will be automatic. And as a matter of statistics *some* servers will run into issues and their owners will be none the wiser, except that a YUM update "killed" their server.

Suggestions?
