It can be much safer to designate a second server with a fresh copy of
the new version of Subversion, Subverison 1.9 if available, to create
a slave of the original repository. This leave the original repository
usable until the final switchover It's especially if the repository
has gotten large, over time, with binary commits and many branches.

Then, when ready to switchover, make a good backup of the old system,
*LOCK IT* to prevent any further ocmmits, and switch services to the
new server. You should be able to activate a proxy or port forwarding
for the old service, if needed, so anyone who accidentally tries to
reach the old one actually gets the new one.
