This is a basic script used to perform a bulk unmanage of nodes. I made this based on input from others in the community. I hope it will help others and make it easier for anyone to understand what to put where. It will unmanage a list of defined nodes. You must have the Orion SDK and PowerShell installed on the machine that you execute this from. It will work with domain accounts. If a node name is not defined or is not found in Orion, it will be skipped.
