Being a totally new server, may I suggest using svnsync instead of a 
dump/load cycle? It's very easy to set up, you can still use the old 
repositories while syncing and if you take care of using the same UUID 
on the new repository you might even be able to make the switch 
completely transparent to the clients.

I did an upgrade about three years ago, I think from 1.4 to 1.6, and I 
used svnsync. It worked very well.

I don't share others' concerns about not upgrading the repository (which 
will happen if you use svnsync). I don't see why now. Besides, using 
svnsync, you don't touch the old repositories at all so you still have 
the old format repos if you need them.

Just my 2p
