We are building out a new WFA environment with Windows 2016 servers and WFA 5.1, but when we do an export of our old database and then try to import it into the new environment, it complains because it cannot support the old "Day-0 Clustered Data ONTAP" pack. But, when I go to the old environment (which was upgraded to WFA 5.1), the option to delete the pack is grayed out, and I cannot delete the workflow or any of the commands that are associated with the pack. How can I get rid of this pack!?!?
