MigrationsMigrations have come up before, and until we survive beta, we're probably going to have to discourage them. If a question doesn't meet the quality criteria of softwarerecs.se, chances are it'll get kicked back to SO. This is true of other beta sites too. Eventually, we'll grow up, be tottering along on our own feet, and be nimble enough to catch or dodge fast moving migrations. Migrations to beta sites are discouraged but not contraindicated,Migrations to beta sites are discouraged but not contraindicated, and may be handled differently by different sites.
So, not yet,unless its an absolutely awesome question that just has to be re-homed. When you do get the ability, please use it wisely.
Do not forget, don't migrate crapdon't migrate crap, there's potential downsides to migrating crap to migration targets, like requests to take those sites off the migration listrequests to take those sites off the migration list, and least personally, I think fixing up questions pre-migration, instead of letting them stumble into the line of fire may improve their chances of survivalchances of survival. If its really bad, don't have any mercy, and just eliminate them on the parent sites .
Having a special mention on SO does seem a little scary though. If we are mentioned, it really ought to be accompanied by a warning or two ;)
