3PlanningThis part of the document contains information about
planning your SAP system update. Before you begin the actual
update, you have to first plan it carefully. This includes
requesting all the SAP Notes you need. Careful planning is a
prerequisite for a successful update. The following information
helps you plan your update so that downtime is reduced to a
minimum, and the update runs as efficiently as possible.When you
plan your update, note the following information in addition to the
information in the Quick Guide [page 17]:?All the times specified
in this document are based on hardware with medium performance
levels.?Do not perform any additional actions during the Software
Update Manager run that could cause it to run less smoothly.?Start
planning your update at least two weeks before you start with the
update preparations.?Only valid for: Source Release = SAP NetWeaver

preparation roadmap steps of the Software Update Manager, Welcome,
Select Target, Confirm Target, Execute Process, Initialization,
Extraction, Configuration, and Checks, as soon as possible. You can
reset and repeat the preparation roadmap steps as often as you need
by choosing Back before you start the actual update in roadmap step
Preprocessing. The successful execution of the preparation roadmap
steps is a prerequisite for starting the update in roadmap step
Preprocessing.?If you are updating a modified system where changes
have been made to the standard ABAP system, you have to start by
updating a development or quality assurance system that has the
same SAP system release (including Support Package level) and
contains the same modifications. The adjustments you perform
manually for the new standard in this system can be automatically
exported to the global transport directory and are integrated into
the update of the production system from there. This procedure
eliminates the need for time-consuming adjustments to the
production system.ActionsThe following sections are important for
