Tools -> Migrate? I haven't tried it myself but I think this is what
it's supposed to do.

You can do it in three steps:

1. Remove the Orange class from the project structure (be sure you keep a
copy, as you'll need it for step 3)
2. Use the extract superclass refactoring on Apple (and extract everything
the Apple has). Call the superclass Orange and place it where the old Orange
was. IDEA will ask you if you want to change usages of Apple with Orange
where possible, be sure to say yes.
3. Overwrite the new Orange class with the old one.

This presumes that the "refactoring" does not cause any problems in your
code, of course. If the original Orange can not substitute Apple then you
will have to update the code.

how would I accomplish this? Both classes already exist, so I can't use a
Rename or Move or Copy, etc... I can't just do a Find & Replace, because
imports would break, and that would find the words "Apple" in places I
didn't want to change.

1. Copy Orange to OrangeX
2. Unsafe delete Orange
3. Rename Apple to Orange and back to Apple (This will handle the imports)
4. Rename OrangeX to Orange

I have a feature request that I created for this a while back:

I don't think the step 3 will work since after renaming back to Apple all
classes will start using Apple and nobody will use Orange

ooooh I want that! That would be very nice.

You are correct. I misread the original question. My example will replace
Orange with Apple.
