This is what I'm doing and so far seems to be working well. OLD = amember 4 v. ..... am_ NEW = amember 5 v. ....am5_ Keep OLD and NEW-ly installed amember tables in ONE mysql directory on server (seems crazy but read on). Upload ONLY the OLD am_ tables for: am_user, and am_saved_pass (You will need to change the prefex to am5_) Now copy and paste from OLD tables (in my case using phpmyadmin) into amember admin interface (after signing in). Otherwise, I get too many errors from uploading the OLD tables into the new amember 5 version with PHP 7. You will have to recreate your products and re-secure your content all over again... but again, do it from the amember front-end interface. Hope this helps someone.
