It's worth pointing out, it looks like this only works in Kilo+, as it's written. Sam pointed out earlier that this was what they'd run it on, but I verified it won't work on earlier versions because, specifically, in the migrate-secgroups.py it inserts into the default_security_group table, which was introduced in Kilo.

I'm working on modifying it. If I manage to get it working properly I'll commit my changes to my fork and send it out.
