Some time ago i purchased a paid Plugin called "RA Simple Sites" Version 0.1 from Ron Rennick to use Domain Mapping for a WPMU Installation. At that time the plugin seemed to me as a good choice because it had support and a very good documentation. It worked up to WP 3.0. Now after I upgraded to WP 3.2.1 the mapping still works, but the option to create new mappings doesn't show up.
I searched a litte bit, but it seems that the further support of this plugin (RA Simple Sites) is only possible with a paid membership. Or if I understand it right there are follow up paid plugins that are called "Networks+" and "Professional Domain Mapping". Because my sites are a litte private project the membership is too expensive for my needs and I'm a little bit confused about the Networks+ or Professional Domain Mapping plugin and wich one I should/could use. Beside of this these two new plugins seems to do more than I need!?
Now I wonder if there is a way to move over to the "normal" WordPress MU Domain Mapping plugin to administer my sites. I already tried to install this plugin and it seems to work, but I don't now how I can import the already existing mappings from the old "RA Simple Sites" Plugin.
Has anybody some ideas?
