Converting from One User Avatar (WP User Avatar)

I’m using One User Avatar for user images. (Previously it was WP User Avatar, but as the new maintainers of that plugin deceided to replace a nice plugin with a bloated thing nobody wanted, One User Avatar was created as a fork.)

Anyway, as your plugin also handles custom images for authors and I don’t want to two plugins for the same functionality, how do I convert these images to your plugin? (It seems like they disappear if I disable the other plugin.)
