Windows 7 RC To RTM?

I am about to start downloading Windows 7 RTM and I currently have Windows RC. I am wondering if I can do a upgrade or do I have to do a clean install.

I think this answers your question:

"Yes, you can continue to use the RC until it expires on June 1st, 2010
(expiration starts March 1, 2010 – this is when the reboots start –
final expiration on June 1). Please note that “in-place” (or direct)
upgrades from the Windows 7 RC to RTM will not be supported. You will
be required to do a Custom installation (aka “clean install”)."

Meh, cba to upgrade before atleast 2010... RC works just fine

well by that time the official windows 7 will be out so why stick with rc? I'm kinda confusedÂ

Uh because configuring windows to my liking and downloading + installing all that shit I want takes alot of my time...
