I’ve been discussing just that with Pete Sharman via Facebook. He has clearly stated almost the exact sentiments as you have, so this being an unsupported process should be expected. Frustrating but the Facebook comments are not updating to the blog post via the plug-in as they have in the past due to an update.

On the subject of no target migrations performed:
From other’s experience and in my own search, the target migration document can only be attained from MOS by contacting them directly with the doc ID #.

While the effort is commendable and i am glad it worked for you, this is in no way a supported mechanism. There are a lot of things that have been missed like targets, security settings, etc that could break the job system and corrupt the repository. Any such undertaking must be done under close supervision from Oracle Support, and should only be tried in dev/test environments.

We plan to support migration of job library in a future release, until then this process should be considered as a hack and comes with no guarantees.
