admin password reset

Hello, I recently inherited a local xwiki site (for internal use), and have no idea of the admin password. Is there any way to recover/reset this? I have a regular user account&password that works. Is there any way to upgrade the user account to an admin account? Alternatively, if I have to reinstall xwiki, is there any way I can save and reload the information? Would mysqldump be useful? Thanks in advance for any help. Sincerely, John G. Apogen Technologies Las Vegas NV Yes, it's hot! I don't care if it's a *dry* heat or not!
