How do I upgrade an older SAP system running on Windows Server 2003 to an SAP release running on Windows Server 2008 R2?

SAP supports the upgrade of an older SAP release on Windows 2008 R2, if your start release is SAP NetWeaver '04 SR1, or higher. For start releases prior to SAP NetWeaver '04 SR1 - for example, start release 4.6C - SAP does not plan to support an upgrade on Windows Server 2008 R2.


You first have to perform a system copy of your SAP system to Windows Server 2008 R2. After that, you can upgrade your SAP system to a higher SAP release. During the upgrade, the productive use of the SAP system is not allowed.

If your target release still supports Windows Server 2003, you can also upgrade your SAP system to run on Windows Server 2003 as well. However, we strongly recommend migrating your SAP system to run on Windows Server 2008 R2.


For more information about the SAP releases that are supported on Windows Server 2008 R2, see the Product Availability Matrix (PAM) at: http://service.sap.com/pam.

For more information about the database-specific SAP Notes for the specific start release, see SAP Note 1476239.

A high-availability (HA) SAP system is only supported as of target release SAP NetWeaver 7.0 SR3 and higher.
If you want to upgrade a high-availability SAP NetWeaver '04 (Web AS 6.40) system, you have to apply the following procedure:

  • You perform a  system copy of your SAP NetWeaver '04 system to a non-HA SAP NetWeaver '04 system on Windows Server 2008 R2.
  • You upgrade your SAP system.
  • You perform a system copy to a SAP NetWeaver '04 system running on a Windows 2008 R2 Failover Cluster.

Do I require a new SAP kernel for Windows Server 2008 R2?

Yes. For more information about the required kernel, see SAP note 1383873 (SMP login required).

Why should I use Windows Server 2008 R2?

The main benefits are:

  • Scalability
    Windows Server 2008 R2 supports up to 256 logical processors.
  • Improved virtualization features
    On Hyper-V in Windows Server 2008 R2, the amount of cores supported by the hypervisor (up to 32) has been enhanced. Another enhancement is Live Migration support by the implementation of Cluster Shared Volumes (CSV). Virtual Machines can be migrated without service interruption between the cluster members. Another new Hyper-V feature, is Dynamic Memory that helps you to use physical memory more efficiently. With this feature, Hyper-V treats memory as a shared resource that can be reallocated automatically among virtual machines.
  • Power usage
    Windows Server 2008 R2 reduces processor power consumption in server computers with multi-core processors using a feature known as Core Parking. Core Parking allows Windows Server 2008 R2 to consolidate processing onto the minimum number of required processor cores, and suspends inactive processor cores. The advantage of Core Parking over traditional servers is 10-15 % energy saving for the same workload.

Can I upgrade Windows Server 2003 or Windows Server 2008 that is running an SAP system to Windows Server 2008 R2?

If you want to migrate an SAP system running on an earlier Windows version to Windows Server 2008 R2, you normally have to perform a system copy. With certain restrictions, you can perform a Windows "in-place upgrade" of an already installed SAP system. For more information, see SAP note 1494740

Can I upgrade my Hyper-V server from Windows Server 2008 to Windows Server 2008 R2?

For performance reasons, no software should be installed directly on a Windows Server 2008 (R2) Hyper-V server. Therefore, your SAP software is running inside a virtual machine, and you can upgrade your Hyper-V server.

Where do I find information about running an SAP system on Windows Server 2008 R2 Hyper-V?

For more information, see Virtualization on Windows.
