       ble  state.   The database should be BACKED UP before running this con-
       version utility.

       WARNINGS:

       Before running the conversion utility, the user must do the following:


                 Back up the database before converting it since the  database
                 will be modified in the conversion process.

                 Disable  the  recovery  log  by  editing  the  tabzero of the
                 database.  After the conversion, the user can  create  a  new
                 recovery log file and enable the recovery log again.

                 Disable  the  audit  trail  by  editing  the  tabzero  of the
                 database.  After the conversion, the user can  create  a  new
                 audit trail file and enable the audit trail again.

                 Resolve all transactions on the database.

                 The Shared Memory part of the database will not be converted.
                 After the conversion, the user needs to recreate  the  Shared
                 Memory partition and remap the tables into the shared memory.
