I would let her loose in one (puppy-proofed) room at first, see how well she adjusts to that room. Then advance - slowly - to letting her free in more area, but always, when you're not there, make sure she can access her crate to have a safe retreat and napping place.

Go slowly, this is to be done on yours and her schedule - there's no exact timetable for any of it, it varies dog to dog!

And eventually you may be able to get rid of the crate entirely, but not for a while yet - and you may find she'll still treat wherever the crate was as her safe place!

That's my take on the situation, but my family never crate trained, I've just experienced it with the dog at work - a different, but similar - situation!
