Description John Matthews 2020-06-18 14:23:03 UTC 
Description of problem:

Below is a known issue for CAM 1.2.x, we intend to fix this with CAM 1.3.0.

Background:
OCP 4.4 introduced a new resource 'ImageTag'
If a customer is migrating from OCP 4.4 and using ImageStreams in those migrated namespaces they will hit a bug in CAM+Velero.  To address we will upgrade to a newer Velero, 1.4.0, but we don't want to introduce the Velero 1.4.0 upgrade in a CAM 1.2 z-stream, we intend to wait till CAM 1.3.0 to officially fix.


Sample known issue text:
"When both source and destination clusters are OCP4.4 or later, attempting to migrate namespaces which contain imagestreams will fail. This is due to the introduction of a new ImageTag CRD which needs special handling in a Velero plugin. We are working on a fix to resolve this issue in the future."
