The devops site is still in beta, so by the companies rules it is not possible to add it to a migration list. The reasoning for this is that sites have to be able to stand on their own and pull in their own audience without relying on network migrations.
Further, I don't think there are sufficient people here who are motivated to do any migrations (anywhere) there were just 32 (away) in the last 90 days.
Personally I'm disappointed that the devops.se site has not taken off as I was hoping it would take away all the crappy questions away from SF.
