I have a live site with amember and lots of members, some paid, some free. I am considering redoing the user interface in Joomla. Would this create any problems? How would I get the existing users into the Joomla database? Other than adding the amember/Joomla plug-in, what else would I need to do to make this work smoothly? Note: I am not talking about getting rid of amember, just replacing the current HTML content pages with a Joomla interface, without losing any current member info.
aMember's Joomla plugin can export all your existing members to Joomla. However, future registrations must be anyway handled ONLY via aMember.
