I have a membership site with about 350 members using WordPress and the plugin Magic Members. I am thinking of moving over to WPMU dev's Membership but I am not sure how hard it will be to transfer membership data over. Most of our members have a reoccurring paypal subscription. Is it possible to get these up and running with out asking members to sign up again? As i fear there would be a large drop of if I had to ask them to do anything.
