I recently had a question migrated from SU to SF that generated the kind of answers I was looking for. In the past I had posted another question to SU that generated a Tumbleweed badge for me, and now I'm wondering if I'd get the answers I'm looking for if I had posted it to SF instead. Technically I'm pretty sure the ability to migrate my own questions from SU to SF is doable- would this make sense as a feature? Perhaps it should only be available once a user has earned a certain amount of rep on the source site? Or perhaps it should cost some amount of rep to perform this migration? Either path could serve to minimize abuses.
I tend to review questions carefully before migrating, and it both these cases I believed they were better answered by a more professional audience, either SF or SO. The problem with this however is unless I do the research for a product I don't know, it may get migrated the wrong direction.
The keywords that triggered the first migration was proxy, server and work followed by the rest, which in my mind immediately triggered the needs of SF. I do however agree with Jeff regarding the second question possibly being better on SO.

In my opinion, a lot of the hardcore, very detailed source control questions belong on SO. I don't know who, other than developers, would know the nitty-gritty details of source control.
