1.2 How this book is organized
This migration and usage guide is intended for use by solution architects and
developers to assist in their migration effort. The focus of this redbook is
migration from Branch Transformation Toolkit version 4.3 to version 5.1,
including migration tools and new development tools.
The migration path covers migration preparation, migrating operation, manual
modification, testing and deployment, as shown in Figure 1-1.
