Problem:
I imported a membership website from Drupal to WordPress via a plugin (FG Drupal to WordPress Premium ). I now have a Custom Post Type (CPT) setup called Membership Profile that have all the user fields setup in it.
My question is how do I put them together so that the WordPress User account is tied together with their corresponding Member Profile?
Solution:
I suggest you setup the author of each "Membership Profile" post as the corresponding wordpress user.
If the custom post type "Membership Profile" is created with Types plugin, you can enable the "author" metabox by this:
Edit the post type "Membership Profile", in section "Sections to display when editing", enable the option "Author", when you edit a "Membership Profile" post, you will be able to setup it's author, more help:

In front-end, you can create a view lists "Membership Profile" posts filter with:
Post author is the same as the logged in user

In the view's loop display a CRED editing form link for user, update the "Membership Profile" post information
