Upgrade Roadmap for Windows/Oracle/SAP from 32 bit to 64 bit

[MichaelTe]

Hello,

what steps do I have to perform when upgrading the following system:

SOURCE:

- OS Windows 2000 32 bit

- Oracle 8.1.6 32 bit

- SAP 46C 32 bit (46D Kernel)

TARGET:

- OS Windows 2003 64 bit

- Oracle 10.2 64 bit

- SAP ERP 2004 64 bit

In which sequence do I have to perform what steps?

First the OS, then the DB, then the SAP?

or something else?

Thanks for any help,

Michael

Michael,

There is information on http://www.sap.com/upgrade-erp, but to sum it up, you always do the following;

OS, DB, then SAP.

Hello James,

thank you for your post. On the website there are more general facts about upgrading to ECC 5.0.

(correct address: http://service.sap.com/upgrade-erp)

My problem is that I want to know how to upgrade the OS and the DB.

But I think the SDN is not the right place for such a question.

Thank you anyway,

Michael,

Did you find SAP upgrade road map ? Wondering if you can share upgrade roadmap docs or point me in the right direction.

Thanks,

Hi Michael

Sorry to open your old thread.

Would you mind sharing your upgrade experience on 32 bit to 64 bit?

We are planning to upgrade our CRM 4.0 (Oracle 10g + Windows 2003 32 bit)

Source:

CRM 4.0 (Web AS 620 + 640 kernel)

Java 620

Windows 32 bit

Oracle 10g

Target

CRM 4.0 (Web AS 620 + 640 kernel)

Java 620

Windows 64 bit

Oracle 10g

I am bit confused about installing SAP CRM on Windows 64 bit software. I understand that you install SAP using 640 kernel for 64 bit.

I would appreciate if you can share your experience or the procedure followed.

After the 64 bit migration is completed, we will be upgrading our CRM 4.0 to CRM 2007.
