0.6.x vice 0.7 compat questions

["Henry B. Hotz" <hotz@jpl.nasa.gov>]

Is the database compatible, or do you need to do a dump/load?   
(Assuming you don't change DB packages anyway.)

I assume the password change protocol isn't changed.

Is the kadmin protocol compatible?  (If not, is it one-way compatible  
where you can use, say 0.6.4 client with 0.7 server, or vice versa?)

Is the Perl admin module compatible?  (with what caveats?)
