To make sure that we can safely transition to CC-BY-SA, we're going to dual-license them under CC-BY-SA 3.0:
I'm not sure this is possible. All approved wikis already have an extensive body of articles in the Incubator licensed under the GFDL. I think these articles cannot be relicensed under a dual-license until we transition to GFDL 1.3.
If this is correct, we can only dual-license new wikis if we purge all their GFDL-only work for the last several months, or wait until GFDL 1.3 is released.
