Migrate2rocky.sh fail

Rocky Linux General
1

Hi
I am migrating from centos 8 to rocky 8.
After running migrate2rocky.sh, the following error occurred.

Is there any way to solve this?

cat /etc/redhat-release
CentOS Linux release 8.5.2111

/migrate2rocky.sh -r
migrate2rocky - Begin logging at Tue Apr 23 01:06:47 2024.

This appears to be an upgraded system where you have leftover CentOS 7 packages. You can try to run dnf update to update those packages to the proper versions, however there is no guarantee this will work.

Upgraded systems are not supported. You are recommended to install a new system and migrate your data.

Thanks.
In the forum, there is a case of successful migration from centos to rocky.
However, migration is currently impossible.

  • centos stream => rocky, centos7=>rocky (X)
  • only centos 8 => rocky 8 (O) = package not supported

That was because it was a true CentOS 8 installation, and not a failed upgraded CentOS 7 installation that you posted about earlier. As already mentioned upgrading from CentOS 7 is unsupported, even if you upgrade to CentOS 8 first, since it’s still been upgraded from CentOS 7.
