Update vault files or not?

Discussion created by Guest on Oct 19, 2006
With major upgrades, do most people update the vault files to the current version? I looked in all the documentation I could find and never saw that this was required but it seems like it should be.

I can't decide which is scarier- running the update on all the files (at least all the "latest versions") in the vault or leaving the files in the older format. Or maybe I'm missing some documentation stating that we need to update?
