You'll need to copy the interface and WTF folders, I believe.
Sometimes its nice to do a fresh install just to clear up old patch remains.
My WoW folder is 27gb, just spent the best part of half an hour transferring it to my NAS :-/
I might just do a fresh install and then copy the WoW and WTF folder back

Anyone else flick back through their screen shot folder to recall on old times ?

Don't you have your WOTLK disk? if so just plonk that straight in, and job done. You don't actually need the other disks.
