This menu is only used for Server Edition systems. Any system being upgrading from pre-Release 10 ADI licenses must be migrated to PLDS licenses before upgrading. This is done using the files created by the license migration tool. However, that tool assumes that the system will also be the licence host. If instead the system is going to use PLDS licenses hosted by a WebLM server, the system's web license server host ID is required in addition to the files created by the license migration tool. This tool generates that additional ID.
