In the first part of the migration process, the utility checks if the ORCL_GLOBAL_USR_MIGRATION_DATA interface table exists in the enterprise user administrator's schema. If it exists, then the administrator can choose to reuse the table (clearing its contents), reuse the table and its contents, or re-create the table. Phase One can be run multiple times, each time adding to the interface table. If the table does not exist, then the utility creates it in the administrator's schema. The interface table is populated with information about the migrating users from the database and the directory. The command-line options used determine what information populates this table.
