If this were possible, then there would be no need for any relicensing exercise.
The data released under CC-BY-SA would be the existing OSM map, and it could
just be used directly with CT/ODbL.

The fact that this is not happening shows that, as generally believed, it is not
possible to accept CC-BY-SA licensed data under a CT/ODbL regime.
