I found this answer to this issue by: @donalyza. He said:
“if you use phpmyadmin, you can easily export the 3 tables related to groups from site 1 and import them in site 2. phpMyadmin has natively import/export tools and avoids you to use an extra plugin to generate CSV or sql formated files.
xxx is the prefix you entered during the wp install. By default it is wp, but it is recommended to use another one. Spambots are too much in love with wp_ prefix. You’re warned ! :d”
I just tried it and it worked, however I had to edit my prefix accordingly to the database prefix I was uploading it to. I used “Coda” to do this, but any similar program works. The site I exporting from had “wp_bp_groups_members” and I changed it to “qou_bp_groups_members” which was the new site prefix.
