If you are not using auto_increment for referential integrity, you could dump your table structure,export all cols but your auto increment, drop your table and re-import your table structure and data. Your idea should also work if you run an ALTER TABLE and DROP INDEX first, then your UPDATE, then re-apply the PRIMARY INDEX .
Either procedure is potentially dangerous and not recommended unless you have a very compelling reason to do so or don't care about the underlying data. In any case perform a complete data dump on the table before trying either method. I hope this helps... Pat...
