Yum repo file and repoid changes:

During the 8.3.2011 release we changed our yum repo IDs and file names to make the process of migrating from CentOS Linux 8 to CentOS Stream 8 easier (sysin).

Repoid (8.2.2004 and before)	Repoid (8.3.2011 and later)
BaseOS	baseos
AppStream	appstream
PowerTools	powertools
centosplus	plus
HighAvailability	ha
base-debuginfo	debuginfo
Devel	devel
BaseOS-source	baseos-source
AppStream-source	appstream-source
centosplus-source	plus-source
base-debuginfo	debuginfo

If you are updating from 8.2.2004 or earlier and have local customizations to the repo files, check in /etc/yum.repos.d/ for any .rpmsave or .rpmnew files that need to be merged. You may also want to update any scripts or tools that you have that specify repo IDs using the --enablerepo or --disablerepo flags.
