If that’s so, it’s rather disappointing. One searches in the forum for how one might migrate one s2 installation to another; amazingly, one finds that it’s not only possible, but looks sort of easy. But only if one has the pro version — which is never mentioned.
I’ve looked at the differences between the free and pro versions — my organization may not have the budget for the pro version, but they also don’t have the need to integrate with anything more than PayPal. Other than the mysterious Import/Export ability, the free version has EVERYTHING we need. Too bad for that — I’d dump s2 for almost any other membership plugin, because of the way this issue has not been handled at all.
