The only way I could see legacy replacement being feasible is if big corp X decided that they were going to do full in house system development, and then market the core or the resulting system to their competitors.

Or do full in house system development and then buy out their competitors. A while back at one of our quarterly IT meetings we had a chart showing this, X number of competitors "recently" bought out, Y number of claims-management systems (and I think other related systems, things like bill review) migrated to our in-house system and shut down, Z number of systems currently being migrated.

That's definitely another angle I hadn't really considered. So would current vendor clients then purchase support packages from you? Or would you encourage their conversion to your new system?
