BuddyPress.org

H there,
I have been using BuddyPress for many years, but no longer need it.
When I deactivated BuddyPress, non of my user avatars displayed in comments, forums, etc.
I noticed the image files remain on the server, but realised that these must be somehow associated with BuddyPress and not WP.

Is there any way to migrate the avatar association back to WP, so that when I deactivate BuddyPress, my users still retain their avatars?

I would rather not keep BuddyPress active just to display user avatars.

Thanks.
