It has been announced that CentOS 8 will be End Of Life in Q4, 2021.  It will be phased out in favor of the CentOS 8 Stream, which falls between the Fedora and RHEL distributions. Instead of CentOS builds after RHEL updates, the CentOS 8 will be the development track for RHEL.  With that in mind, there is a path to “upgrade” or “migrate” from CentOS 8 to CentOS 8 Stream.  It is easier than one would think.

dnf install centos-release-stream
dnf distro-sync
dnf update

Check out the version.

[root@c8-template ~]# cat /etc/redhat-release
CentOS Stream release 8

That is it!
