I created a job driver and associated trigger job in one IDM
environment, then used Designer to migrate it to another tree. The job
driver starts and runs, but the job doesn't show up at all. When I
click on the 'Jobs' tab in iManager, nothing happens. I've verified that
iManager has the latest snapins.

I later noticed that the source tree has an IDM 4.6 server in it, while
the destination tree has IDM 4.0.2, so I'm guessing it's a schema issue.
Do I need to deploy an IDM 4.6 server in the destination tree, or can
I just update the schema from the IDM 4.6 install media?
