About 3x.

Yes, that's the way it's designed. The library can run either engine. You pick one when you construct the stretcher object, and the rest of the API and the way you use it are identical.

In principle to switch an application from one to the other is simply a matter of adding "| OptionEngineFiner" to the end of the options list when the existing code constructs its stretcher. (I say "in principle" because you would want to test it thoroughly and check that it is actually doing what you expect!)

It is also usually a good idea to call the new function getEngineVersion() after construction to check you have the engine you expected, because that guarantees you don't accidentally get linked against an old library version that doesn't support the new engine.
