How to migrate from CentOS 8 to Rocky Linux 8

NOTE: UPDATED ON 30 Nov 2021 for Rocky Linux 8.5

Rocky Linux 8.5 is released today. I already added support and wrote down instructions about how to install PostgreSQL on Rocky Linux 8, and now it is time for a short blog post about migrating from CentOS 8 to Rocky Linux 8. Please note that if you are using CentOS 8 Stream, this blog post is not suitable for you.

These steps are experimental for now -- use the instructions at your own risk. It worked for me, though.
