Please read this thread. Relevant for the later versions also.
If you are developing C-mode DR workflows, I would request you to look into 2 workflows.
1. Storage Virtual Machine config replication workflow. This is PS supported. You need to contact Professional Services.
This will copy the configurations to a SVM DR destination, but won't copy the data. This will work with 8.2.0 and WFA 3.0.
2. If you wait for a few more days, then you will get a bunch of SVM DR workflows which will work with ONTAP 8.2.1
and WFA 3.1 ( not released yet.. but waiting at the gate to be released by end of this month).
Let us know if you need any more clarifications.
