Q7: How do I migrate my CentOS Linux 8 installation to CentOS Stream?
A: Instructions to convert from the CentOS Linux 8 distribution to CentOS Stream 8 are published at https://www.centos.org/centos-stream/ and are also below for your convenience.
[root@centos ~]# dnf swap centos-linux-repos centos-stream-repos
[root@centos ~]# dnf distro-sync
This will result in some package updates and new packages being installed, which is expected.
