We migrated from 6.2.5 to 7.3. Worked fine in 6.2.5 but that was a resource operation on the VM. Now it is on the Deployment.
Our workflow is flipping the owner on new deployments but I have checks in place to wait for all of the resource operations to be in place and make sure all assets are returned via the api. My testing is being done on systems that have been around for days. I can login to the gui with the same account that I am using in vRO and change the owner without issue.
