Well, if you need the data for personal use - you can use them even
with mixed license. If you need to distribute them, etc ... you could
filter the cc-by-sa data out.

This would allow the remaining cc-by-sa data to be iteratively deleted
and then redrawn under "correct" license. I think this could be
viable, if there would be only small part of such data. (so the period
in which the data won't be properly distributable will be quite small,
perhaps few days till all is redrawn)
