Description John Matthews 2019-09-03 15:09:12 UTC
We want to include a note in migration docs that for OCP 4.2 when migrating a namespace we will preserve the annotations on a namespace of:

"openshift.io/sa.scc.mcs"
"openshift.io/sa.scc.supplemental-groups"
"openshift.io/sa.scc.uid-range"

This could lead to potential overlap of UID ranges in namespaces on destination cluster.


In next release (OCP 4.3 timeframe) we will make this step optional so a user can opt out of it.
