I came across this forum post-
The KB article doesn't appear to be available to customers- likely because it involves directly modifying a database table. (Some KB articles are available only to resellers for reasons as such).
I believe this would best be addressed through an enhancement request for the ability to do so in the user interface, rather than risking a botched database. If this is addressed through an ER then it would be supported in the future- modifying the database table directly would never be supported.
