@ -16,15 +16,22 @@ Running this script will convert an existing CentOS 8 system to Rocky Linux 8.
### Known Issues
#### Katello clashes
#### Custom replacements of default repositories
Katello installs its own repositories via subscription-manager that are meant to
replace the ones from CentOS, but it does not remove, or even disable, the
corresponding CentOS repositories. This would cause issues to a normal running
system, but it is especially problematic for migrate2rocky as it means that
migrate2rocky cannot properly determine which repositories to remove and
attempting to run migrate2rocky on a katello will likely result in a corrupted
system.
This script expects the **original repository configuration being present, as well
as enabled** (i.e. for CentOS the `baseos` repo configuration in the
`/etc/yum.repos.d/CentOS-Linux-BaseOS.repo` file has to be present and enabled).
Also make sure that there are **no other repositories** which could interfere with the
original configuration.
Any distribution that has had its core repositories altered, removed, duplicated
or overridden may cause migrate2rocky to break or corrupt the system when run.
Any attempt to migrate such systems, even after reversing the changes made by such
software, is not supported in any way. In all cases you should backup your system
before using migrate2rocky and USE AT YOUR OWN RISK.
This especially happens on systems configured with a centralized package management
like Katello (RedHat Satellite 6) or Uyuni (RedHat Satellite 5, SUSE Manager).
#### RHEL migrations show error messages during conversion
