You can download all the member's email address's, options etc etc and save it in a data base that can be played with and such.? If you have a free account with groups.io this is the way to move members over real easy.? Just cut and past the information into your members invite panel and bulk send out.? The only thing that you can not do is move over the message data base.? The pictures and files you can yourself.? However the groups.io file and folder panel is rather primitive and not very fast when you have say 2,000 pics to move which I have to do on some accounts.
