I ran the moveData command in my dev farm after pausing the timer service and stopping the web application. The command completed and I restarted the service and the web app as prompted in the powershell command window after the command completed.
I can see that the data has been moved into the new Nintex DB, which I created and mapped prior to running the movedata command. However, when I go to view the history of an old item or the task of a current item I get an empty page for the former and an error on the latter saying it can't find a task with that id.
I followed the guidance found here. After seeing the results I issued an iisreset and eventually even rebooted, in case there was some voodoo moves required, to no avail. Is there something I can do to force SP to recognize the new Nintex content DB?
