Description
Although the average SAP customer tackles an SAP upgrade project every three years, it is still often very challenging to comprehend or calculate the impact of such an undertaking. Further complicating matters, the upgrade process has changed dramatically from the old releases (up to 4.6C) and the current releases (ECC 5.0/Web AS 6.40 and above). This new technical guide from the SAP PRESS Essentials series discusses the upgrade from a project management, customization, development and technical point of view (execution of the PREPARE and R3up phases). 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 bases are covered, including how to plan the upgrade project and the impact on the system landscape during your SAP upgrade.
Highlights include:
Overview over SAP upgrade projects
Technical background
Upgrade tools
Preparing the upgrade
PREPARE process
Upgrade process (R3up)
