How to import Wordpress users into una.io

Hi! I'm considering using una.io for a future iteration of our nonprofit community website (which is currently hosted with wordpress and a membership plugin). It's looking like una by default does everything that's been really difficult to figure out with wordpress.

If I had to I could probably ask our members to create new accounts on the una.io version of the website, but there are thousands of them, and it would be really nice if at least some of their data would transfer over! Anyone here have experience with migrating from Wordpress to una.io?
