I need to move my aMember installation from WordPress to Drupal. Has anybody done this? Please let me know if there is an easy way to accomplish this. Thanks.
You should configure Drupal first (and move your content into Drupal). Then install/configure Drupal plugin into aMember, assign drupal groups to amember products at aMember CP -> Manage products -> Edit Product and click Rebuild Db. All active users will be transfered to Drupal automatically.
