If the processor architectures differ, copying the repositories directly
won't work unless changes to the repository format have been made
recently. I had a problem when copying a repository from a 64-bit x86
machine to a 32-bit x86 machine, for example. (I think this was in
1.4.x, but it was years ago and I don't remember the details.) Solaris
10 suggests a SPARC machine as the source. Because of the byte ordering
difference, I'd expect major trouble when copying a repository directly
from a SPARC machine to an x86 machine.

I've used (and recommend) the svnsync approach recommended by another
poster. Downtime can be even less than when copying repository
directories directly.
