Selecting the Optimal System Landscape for Your SAP R/3 Upgrade Project

  • by Arthur Miller, Manager, Upgrade Competency Center, SAP America

An R/3 upgrade requires that changes be made to the new system, and it requires support for ongoing changes to the production system as well, so the underlying system landscape must make it easy to manage change. Most upgrade projects use a variation on one of two landscape strategies: rehearsal of the upgrade process on a separate, standalone R/3 sandbox system, with the intent of rolling out the upgrade to the production landscape at a later time, or upgrade of the production landscape's development system right away, followed after a time by the upgrade of the QAS system, with the maintenance of additional, temporary development and QAS systems to support the production system at the old release. Understanding the principles, benefits, and limitations of each of these strategies will help you decide which approach best suits your upgrade project.
