This significantly extended and completely revised 2nd edition of our best-selling reference book helps you drastically reduce the cost and duration of key data migration projects. This comprehensive reference book is focused on helping you avoid the need for programming by using batch input, eCATT, CATT, and the Legacy System Migration Workbench (LSMW).

You'll learn how to optimize these tools for data migration and where exactly manual customization might be needed. The various individual methods are compared and contrasted, enabling you to gain valuable insights on the technique that most closely matches up with your individual requirements. In addition, you'll benefit from a detailed introduction to the new Accelerated Data Migration tool (ADM), which enables you to migrate large quantities of data faster than ever before.

Specific chapters deal with asset migration and data staging as they relate to migration project preparation. These key chapters also provide you with useful information on how Microsoft Access and Excel can be used to cost-effectively prepare your data for migration.
