Svnsync can be run anytime without bothering the working repo very much
so you can have most of the contents in the new one well ahead of time
and repeated runs pick up where it left off. You just need to make sure
that no commits are done while you make the final run before the cutover
- which can be very quick.

I think some people here have mentioned a binary library tool that rotates your binaries... or I can just add it to my nant scripts like I currently do it with test installers.

If you come up with a good scheme for this that doesn't interfere too
much with using externals to pull in component libraries without
recompiling, please post it.
