Does the migration script work on CentOS 6? I have an old server still running CentOS 6, and the reason why I never upgraded to CentOS 7 on it was because some package didn’t have a compatible replacement (some fonts package if I remember correctly), which didn’t seem like a big deal, but I considered it too risky since it’s a server at a data center that I don’t have local access to. Has anyone upgraded from CentOS 6 using the migration script? Did it work OK? Is that even supported? I’ve migrated several servers running CentOS 8, and the script works great, but I haven’t tried it from a CentOS 6 or CentOS 7 server yet. Wondering if it will work OK… Please let me know. ---

migrate2rocky does not support migration from EL6 or 7 due to the large number changes made in each major release. Alma Linux has a script called `elevate` which claims to be able to migrate CentOS 7 to Rocky Linux 8, but I don’t know if it can migrate from CentOS 6 (I rather doubt it). Regardless elevate and the machines migrated using the elevate tool are not supported by Rocky Linux and you do so at your own risk. ---

Each major release is substantially different from each other. Translation of service config from one to another is non-trivial. Even format of RPMs evolves. There is no “upgrade script” that could cope with every possible setup. > [@own3mall](#): > > … it’s a server at a data center that I don’t have local access to. No out-of-band access (like Dell idrac, HPE ilo, ipmi, kvm, etc)? _What if_ something else goes wrong? Say, the kernel dumps core (which is luckily rare). How do you cope with those? ---
