Basically OP wants to upgrade from 1.4 to 1.5 and wants to know how large
the dump file size is going to be. From the question it seems like he also
had a hot copy. I guess my answer was for him to try the 'svnadmin upgrade'
on the hot copy and if it works, just do the same on the actual repository,
instead of doing the dump.
He could do the 'svnadmin upgrade' on the svnsync-ed copy as well.. I have
no issues with it ;-)
