Using mod tools make this kind of list easier to make. Anyway, for February, here is the break-down of where questions were migrated away from ServerFault. I didn't go into any additional stats (mod-hammer vs. vote-to-5) or what happened when they got to the destination site since I'm on a crap network and that kind of loading may just kill it.

    Destination   | Count
    ------------------------
    StackOverflow | 14
    SuperUser     | 133
    Meta.SF       | 1
    WebMasters    | 40
    ------------------------
    Mod-moves to any site:
    ------------------------
    AskUbuntu     | 5
    Apple         | 3
    WordPress     | 2   
    Unix & Linux  | 8
    WebApps       | 2
    Security      | 1 

209 migrated questions, of which 63.6% went to SuperUser. What's interesting to see is that migrations to WebMasters outnumber migrations to StackOverflow.
