Converting a database from release 15.57 or 16 to release 21
To use this procedure, your option 51 must currently be running version 15.57
or higher. If your system is running an earlier version of release 15 software
(release 15.53, for example), you must first convert the database to
release 15.57. Refer to Software conversion procedures (553-2001-320) for
instructions on converting the database to a higher version of the same release.
Only those systems running release 15.57 or 16 can use this procedure.
