There’s not a clear path honestly, since everyone’s installations can be markedly different. To guess at exact SQL queries you would need to run would do more harm than good.

If it was me, I would spend a lot of time analyzing the data in the 2 databases with something like phpMyAdmin, and come up with a plan on how to combine the two databases and WordPress/bbPress users tables together into 1.
