We have looked at this in the past and decided that the only one we
needed to increase was for keys.
This is when the script "migrate_id_mysql.pl" was created. (As you can
see it is not as simple as just changing the column type; you need to
drop and then recreate the FK constraints also.)
Does anyone think that these fields need to be increased?
