Description Sonal 2023-06-02 14:08:38 UTC 
Describe the issue:

ODF upgrade process involves downtime (of very short time though) for applications using ceph/rbd pvc and noobaa obc, as there is a single instance of mgr running. Similarly, as there is a single instance of noobaa-db running, upgrade cause downtime of s3 applications.

The document should add a note about it so that admins are aware of it (as some customers run senstive workload on ODF)

Describe the task you were trying to accomplish:
Upgrade ODF 4.x to 4.y

Suggestions for improvement:
Add a note in the "Updating OpenShift Data Foundation" document that there will be downtime of a few minutes during ODF upgrade.
