Possible Duplicates:
Can SO/SF/SU questions be migrated to beta sites?
Will it be possible to migrate questions between the trilogy and the Stack Exchange 2.0 sites?
I'd like to suggest a migrate to Stackexchange site option, as suggested here:
Expand the comments. It's in there.
You can migrate to the trilogy sites from any of the other two. A lot of questions from SO and SU may be more specific or more on topic on Apple.SE or Programmers.SE.
