RHEL 7 to CentOS 7 migration tool

Usage

In order to convert your RHEL 7 operating system to CentOS 7 do the following:

1. Make a backup of the system. We didn't test all possible scenarios so there is a risk that something goes wrong. In such a situation you will have a restore point.
2. Download the migrate_7.py script:

   $ curl -O https://raw.githubusercontent.com/cloudlinux/rhel2centos/main/migrate_7.py

3. Run the script and check its output for errors:

   $ sudo python migrate_7.py
     ...
     The system is migrated to CentOS 7

4. Ensure that your system was successfully converted:

   # check release file
   $ cat /etc/redhat-release
   CentOS Linux release 7.9.2009 (Core)
   
   # check that the system boots CentOS kernel by default
   $ sudo grubby --info DEFAULT | grep CentOS
   title=CentOS Linux (3.10.0-1160.31.1.el7.x86_64) 7 (Core)
