It has been my experience migrating a number of customers to Cayenne from WO over the years, that a if planned properly, a rewrite may not be as scary as it sounds. Essentially it becomes a part of planned evolution. Since Cayenne and WO apps can share the same DB, you simply keep your old WO apps around. But sooner or later a time comes for each given app when a change request arrives that requires a substantial rewrite / extension. This is when you make a jump to a new stack for this particular app. And in couple of years you find yourself completely on a new platform :)
YMMV of course. A.
