Linux Magazine, January 2003, page 28.  Article by Jeremy Zawodny.

Too long to quote directly.  Relevant section is headed 'Compatability'.  The 
short of it: the on-disk format didn't change between MySQL 3.23 and MySQL 
4.0, so you don't need to do a massive export and import process.  You will, 
however, need to run mysql_fix_privilege_tables to update the grant tables to 
use the new privileges features in 4.0.  Also, and I'll quote this one: 
"Moving to MySQL 4.1 will require you to either dump and re-import your data 
or run various ALTER commands to take advantage of its new features.  
However, if you don't need those features, your existing tables will work 

It's that last sentence that has me perturbed.  It is just so obvious a
