Hi,
I've recently done some extensive testing with the centos2ol.sh migration script provided by Oracle:
https://github.com/oracle/centos2ol
The script works perfectly on both CentOS 7.x and 8.x, so I wrote a little blog article about it:
https://blog.microlinux.fr/migration-centos-oracle-linux-cas-pratique/
I wonder if something similar exists for other use cases, e. g. migrate from CentOS to Red Hat Enterprise Linux.
Why I'd like to do this? Well, a significant part of my work is teaching Linux and writing books about it. My last two books have been based on CentOS 7.x, and I'd like future editions to be distribution-agnostic within the RHEL family. This is now an option since Red Hat offered free Developer subscriptions a few days ago.
In other words, future blog articles and book chapters will be based on RHEL (the real thing), but I'll also test everything with the various clones, namely Oracle Linux and (probably) Rocky Linux as soon as there's a usable version.
Public server providers like Scaleway offer the "usual suspects" among distributions, e. g. Ubuntu, Debian, CentOS and FreeBSD. So I'd like to know if there's a script out there that converts an existing CentOS (or Oracle Linux) installation into a RHEL system.
Any suggestions ?
Cheers,
Niki
