In spite of the fact that Jeff was against the idea of migrating from MSO to SO it would appear that it is now possible to do so since this question was.
However, the "migrated from" footer is not there. To get the link that shows the question on MSO I had to hand-craft the URL with the ?noredirect=1
at the end of the question URL from the question list.
Can we add that footer?
To be clear, this question on Programmers.SE was migrated from Stack Overflow and does have the proper footer there (which allows you to click back to the closed Stack Overflow version of the question)
edit: it appears this may have been a result of a diamond moderator migrating and then clearing the migration history, if this could be confirmed I would accept that as the answer
