Unified Manager 7.1 requires OnCommand Workflow Automation 3.1 or later to provision Storage Virtual Machines (SVMs) with Infinite Volumes with storage classes, and to configure SnapMirror and SnapVault data protection relationships. Workflow Automation 4.0 is recommended.
Note: Please consider WFA 4.0 was the latest GA release at time this documentation was written (hence why it's recommended).
Also what version of DataONTAP are you running in your environment. It's import to consider this during your upgrade planning.
EG Ontap 9.X requires OCUM 7.X which requires WFA 3.X etc.
