Dear friends,

One of the customer wanted to upgrade SAP 4.7 system to ECC 6.0 EHP6.

Source System:

OS: Windows 2000 NT 32bit

Database : MS SQL 2000 32bit

SAP 4.7 Non-Unicode

Target System:

OS : Windows 2012 64bit

Database : MS SQL 2008 R2 64 bit

SAP ECC 6.0 EHP 6.

Could you please any one share the experience and what way to proceed this upgrade.

Thanks & Regards,

Hi Srinivasan,

You may need to follow below steps

1) Install a new target system  R3 4.7 Unicode with MSSQL 2005 on Windows 2003 .

2) Perform Unicode conversion of R3 4.7 non-Unicode -> R3 4.7 Unicode on the system built in step-1 using Unicode conversion method.

3)  Perform SAP upgrade to ECC 6.0 EHP5 on the target system running with MSSQL 2005 on Windows 2003.

4) Post upgrade to EHP5 perform homogenous system copy to MSSQL 2008 R2 running on Windows 2012 64-bit.

5) Perform upgrade to EHP6 with MSSQL 2008 R2 and Windows 2012.

As per PAM, ECC 6.0 EHP6 can run only on Windows 2008 or above while R3 4.7 is not compatible with Windows 2008. Hence you are required to follow such an approach.

Below links are details from PAM

For R3 4.7

Hi Deepak,

Regarding SUM (software update manager).

I want to upgrade R/3 enterprise 4.7x200 to ERP6.0 incl EHP6. Therefore SUM should be the tool to use.

In a early stage the SUM asks for: "select target system version". 2 opties: Stack configuration file (XML) of course generated by MOPZ. This is not an option for me as for now since we don't have an active Solman yet (still needs to be installed). 2nd option is: manually prepared directory. However this option is not selectable..!? My thoughts are that this is because it handles a version upgrade and therefore maybe not possible??!!? What other option are there? Any advise is appreciated!

Thanks in Advance.

Hello

I see a copy paste of a question from the toolbox forum.

http://sap.ittoolbox.com/groups/technical-functional/sap-basis/upgrade-r3-enterprise-47x200-to-erp60...

What is your problem ?

Have you read the suggestions given there ?

Read this SAP note :

Note 1641062 - Single component update and patch scenarios in SUM

Create a sandbox system by creating a copy of the existing system and perform the upgrade there and see how it went.

Check these SAP notes.

Note 335690 - Special Support of DB & OS releases for SAP upgrade/installa

Note 666805 - MS SQL Server: Migrating from 32-bit to 64-bit

Note 683447 - SAP Tools for MS SQL Server

Note 960769 - Windows: Migration from 32-bit to 64-bit (x86_64)

Note 151603 - Copying an SQL Server database

Hi Srinivasan

Please check PAM if ECC6 is supported on Win 2012.

As far as i know Win 2012 is not yet officially supported - the highest is 2008 R2.

(It doesn't mean that it won't work - but you may encounter issues....)

Hello All,

I need to perform SAP system copy in SAP R/3 4.7 running on windows 2003 and SQL server 2005 to windows 2008 and sql server 2008. Can you please let me know what are steps I need to follow on this.

Do I need to take export of t the existing CI or I can create new instance and restore the backup of source system.

Please suggest me best practice to perform homogeneous system copy.

Thanks,
