How to migrate CentOS 7 to Rock Linux 8

Hello. Some of my servers are on CentOS 7 operating system. The documentation for migrating to Rocky Linux is for CentOS version 8. How can I migrate from CentOS 7 to Rock Linux 8?

I’m in the process of doing that upgrade myself, but a fresh install is the way to go I think, then copy over things from the old Centos 7.

The recommended way forward is a migration. One of these things could be done:

  • Backups of data are taken and restored on a freshly installed Rocky 8 system
  • A new Rocky 8 system is installed in parallel of your CentOS 7 machine and you perform a migration of configuration and data
