[RWP] Migrating Project

[indigo]

I just made the basis of a nice project, but on this old machine with no 
real sound card, effects, everything I need.
So, how do I migrate a Reaper 4.21 project from one computer to another?
Both computers have Reaper 4.21 installed, and both are running  32 bit 
XP, so no problem there.
Is it as simple as copying the .rpp file onto a thumb drive and pasteing 
it into the Reaper Media folder on the other computer?
I only use this old beater for email and surfing, and keep Reaper on it 
to pop into to make sure I'm getting rterms right.
It sort of crept up on me, and before I knew it, I'd made something nice 
I don't want to lose, but not mixed down  on a 1995 SoundMax chip. smile.
Thanks,
