SAP Server upgrade from Windows 2003 and 2008 R2 with Oracle Database

Hi,

We need to upgrade upgrade our Windows servers that are running our SAP systems from Windows Server 2003 to Windows Server 2008 R2. We are using Microsoft Clustering for HA so an inplace upgrade seems not possible.

Someone has suggested to us that we will need to export our database and reimport it to achieve this upgrade however but I cannot understand why this would be necessary (we are not changing the underlying filesystem!).

Could someone please confirm whether a database export and import is required for this OS upgrade scenario? I have done a bit of research but nothing has jumped out and now I need an answer to this quickly.

We are running

- ERP 6.0 NW 7.01 (soon to be 7.02 with ABAP stack only)

- XI(PI) Java & ABAP

- SRM (Java & ABAP)

- Portal (Java only)

- PLM (Java & ABAP)

- BW (BI 7.0) (Java and ABAP)

Thank You

Felicity

    Hi,

    You can achieve your desired results using homogenous system copy procedures. Follow either of the process

    1) R3load procedure of export / import

    2) Backup restore

    Hope this answers your query.

    Hello,

    You need to go for 'Homogeneous System Copy' to achieve this, but since almost all the systems in your landscape include the Java Stack as well - so the system copy with Export/Import is to be carried out.

    Even if you are not going for file system change, but it is a Windows environment and you can't put SAP up on the target Windows (windows 2008 R2) just by copying the contents and file system from source to target. You need SAPinst to create the registry and all. - On top of that you have Java stacks involved, so for java stack you can't carry out just backup/restore method to put SAP up there on target - so you need Export/import because for java stack some OS level dump is to be collected during system copy from source and it needs to be imported on target OS.

    Are you clear on this one ?

    Read system copy guide once and Search in OSS for the Notes to check how to upgrade from Windows 2003 to Windows 2008 R2.

    Thanks

    hello,

    An "in place" upgrade of the os is also supported.

    note 1494740 SAP system migration from Windows 2003 to 2008 (R2)
