Speaking of sample rates: I want to increase from 48k to 96k on work in progress. Advice?

So I somehow accidentally (or forgot that I did it intentionally) set my current project to 48khz but want to record the final tracks at 96khz. The only audio currently in the project is a single guitar track I'm using as the bed. It will not be appearing in the final project. Other than that there is only my Addictive Drums MIDI track using multiple outputs (not bounced or anything).
 
So how would I go about upsampling this while keeping the guit track as a useable bed? I don't mind a slight deterioration of sound quality on the bed track as it will not be used anyway. I just need to be able to play over it while I record the final takes. Want to do this before I start recording bass parts.
 
And this won't affect my MIDI drums will? Anything else I should watch out for?
 
BTW I tried dragging the MIDI and audio clips into my 96khz template but it wouldn't allow me to drag drop the audio from one project to the other because of the samplerate discrepancy... thus my question.

I also had this occur in one of my projects that Id started earlier in MC6 at 44.1 KHz. I redid the entire thing in midi because the audio records were crap, so now I hope I can just delete the old tracks and change it to 96 bit.

Thanks Mettulus. I was going to do that as a last resort but I guess that's how she's gotta be. Not really a big deal with a single audio clip but that would be a nightmare on a larger project. I find it odd that it didn't just automatically convert it to the new sample rate. I've done that type of thing before but I guess it was a higher samplerate going to a lower setting... or maybe it was just bit depth... or maybe I had another one of my sheer insanity moments and dreamed/hallucinated the whole affair.
 
Now I have to figure out what'll happen with the MIDI clip. I'm ASSUMING that I could just drag it in (didn't try that yet) or import it. Samplerates don't affect raw MIDI data do they?

We just went through a epic battle over this.  Again what you get with a higher sample rate is greater bandwidth not greater accuracy. 

Of course it can hurt, using higher sample rates make the PC work harder to produce the same end result. The harder the PC has to work, the more difficult it can be to work with the project. The cautious approach would be to avoid testing the limits of the machine.

Yeah but my system should be powerful enough and now that I know about the Read/Write cache settings and other resource saving tricks even ridiculously large projects are fine.
 
The fact X3 is actually pretty darned solid helps a lot too.
 
BUT... now that you mention it I'll keep an eye on such things once I make the conversion so a useful post as always, scook.

If my PC struggles with 96 KHz, I'll just be mad.
