With release 7.0 (the basis of SAP ERP 6.0), SAP undertook a complete revision of the upgrade procedure of NetWeaver AS. Now, it is also possible to upgrade so-called "double-stack" installations; those with both an ABAP and a Java stack under the hood. This comprehensive guide covers all kinds of SAP upgrades. It describes a complete project, explains project management questions, provides technical background information (also on the upgrade of other systems like CRM, SCM, and BI), and then walks you through the project steps - from A to Z.
The authors cover the entire process in detail - from first picking up the upgrade manual, to sending an e-mail to management, informing them that the system is now running the new SAP release - and every step in between. All of the basics are covered, including how to plan the upgrade project and the impact on the system landscape during your SAP upgrade.
The first edition of this book was published as an SAP PRESS Essentials guide under the title "mySAP ERP Upgrade Project Guide".
Topic highlights include:
- The upgrade project
- Upgrade tools
- The PREPARE process
- The upgrade process (SAPup)
- Upgrade post-processing
- Modification Adjustment
