@mostafa As you know, the procedure you attempted to use is _NOT_ supported by the Rocky Linux team. The only supported move from 8 to 9 is a clean install and a restore of a data backup. You can use [this procedure](https://docs.rockylinux.org/9/guides/update_versions/) to do exactly that. There is no supported tool or method to move directly from version 8 to 9.
