avatar paths didn't migrate when site was moved?

I only know this because we have looks at the source code, but when we migrated our site, the avatars for Ultimate Members did not migrate/change when we changed the site URL. Is there a step we need to add to make sure we get UM to change over as well? Is this actually a sign that we may be having deeper problems with the plug in changing over to the new url?

Thank you!
