How to export from old db, and import into fresh new v4.7 db

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.
