svnadmin setuuid — Reset the repository UUID.
Reset the repository UUID for the repository located
at REPOS_PATH.
If NEW_UUID is provided, use
that as the new repository UUID; otherwise, generate a
brand-new UUID for the repository.
If you've svnsynced /var/svn/repos
to /var/svn/repos-new and intend to use repos-new as your
canonical repository, you may want to change the UUID for
repos-new to the UUID of repos so that your users don't
have to check out a new working copy to accommodate the
change:
$ svnadmin setuuid /var/svn/repos-new 2109a8dd-854f-0410-ad31-d604008985ab
As you can see, svnadmin setuuid has no output upon success.
