After you have tested the RACF® data base to ensure that the conversion was successful, you can delete information from the UADS for user IDs converted to the RACF data base. To delete information from the UADS, use the DELETE subcommand of ACCOUNT.

Do not delete information from the UADS until each user logs on to TSO/E for the first time after the conversion. User information stored in the UADS must be available to obtain a user's current user profile table (UPT), because the conversion does not migrate the UPT to the RACF data base.
