This command executes the migration of existing accesses within the Core Database. Each access stored in the Core Database is enriched with the unique identifier of the subscriber account related to the charging contract or subscription which is referenced by the access. Storing this additional information in accesses gives the possibility to increase the vertical scalability of the rater instances.

Accesses are spread over 240 database partitions. This command takes the number of partitions to process as argument, so that the migration operation can be executed in several increments.

The accesses are updated using a batch mode. In case an error occurs while processing a set of accesses, the execution of the command stops. Executing the command again resumes the migration operation from the set of accesses where the error occurred.

All SAP CC instances but the updater instance can be running while executing this command.

After executing this command, it is necessary to complete the migration of accesses for guider instances using the CC40SP08_CompleteAccessMigrationForGuiders command.
