admin password reset

[john.goetz at qn.niat.net]

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,

Yes, it's hot! I don't care if it's a *dry* heat or not!
