Bulk Data Transfer (BDT) is a licensed program that transfers data from one computer system to another. The type of data that it transfers depends on which of its features is installed:

• The File-to-File feature allows users at one z/OS JES2 or z/OS JES3 system in a SNA network to copy data sets to or from another z/OS JES2 or z/OS JES3 system in the network.
• The SNA NJE feature allows z/OS JES3 users to transmit jobs, output (SYSOUT), commands, and messages from one computer system to another within a SNA network. Any of the following systems can participate in the network: z/OS JES2, z/OS JES3 (with BDT), VM/SP (with RSCS Networking), and VSE/Advanced Functions (with VSE/POWER).

This chapter presents an overview of the migration considerations and installation procedures described in this book. They are:

• Planning your migration
• Planning your configuration
• Defining BDT to MVS
• Defining BDT to VTAM
• Allocating BDT and TQI data sets
• Formatting TQI data sets
• Creating a BDT initialization stream
• Writing BDT and TQI start procedures
• Writing user exit routines.
