Much, much faster and safer: Create a 1.7 "svnsync" against the 1.5 repository. Test dumping and loading from *THAT*, on your 1.7 enabled host. When fully tested, lock the 1.5 repository, and replicate or switch to the 1.7 repository, with the new uuid set manually. This gives you much less downtime and reduces the reisk of "split-brain" behavior. This is also the size of repository where you might want to consider commercial support, or seriously consider fragmenting that repository. Backups are going to take a while, restores longer, and you're at serious risk of having a single corrupted revision cost you enormous engineering time.
