I need to correct something I stated, which is this:
"If you are moving to WFA 2.1, and UM 6.0, UM 6.0 only monitors clustered ONTAP. This means no protection manager and no resource pools."
There are indeed resource pools in OnCommand Unified Manager 6.0. That said, the database behind UM 6.0 is different from that backing the UM 5.x versions, so yes... if you were looking to use Resource Pools in a WFA workflow using UM 6.0, then yes, you would still have to rewrite your workflows.
I was also informed that the sample workflows coming in WFA 2.1 use the UM 6.0 resource pools.
Sorry for the confusion.
