sap 4.6c to ecc6 upgrade

Dear friends,

Would you please tell me the main steps of upgrade our SAP system from 4.6c to ecc6 upgrade?

our database is oracle. our system platform is MS windows server 2008 R2.

In my opinion,

1.create a ECC6.0 system in our target server with empty database

2.system copy from source system to target system

3.upgrade our target system by SUM tool

Is it correct?

Thank you in advance!

    • Hello Chen,

      System Export/Import is nothing but system copy only. Since both are windows, you can perform homogeneous system copy.

      So your steps would be like this.

      1. Upgrade Oracle to 11.2.0.3 on 4.7 32 bit server (Windows 2003)

      2. Prepare system for System copy

      3. Install SAP R/3 4.7 with Oracle 11.2 on 64-bit Server (Windows 2008 R2).

      4. System copy from Windos 2003 to Windows 2008

      5. Run SUM to upgrade it to EHP6.

      Give a try. All the best.

      Best regards,

      Srikanth

    >>our database is oracle. our system platform is MS windows server 2008 R2.<<

    Does this mean the system to be upgraded is already running on Windows 2008 R2?

    If yes you can skip the system copy and start the upgrade.

    • As you are doing an Oracle upgrade on the source system then things will be easy. You can trigger System Copy - Target System creation or and SAP and Oracle installation on the target server and perform a backup and restore of the database. Once the system copy is done you will need to start the upgrade without using the system for production. In that case the sequence will be like this:

      1 - Upgrade Oracle on the source system.

      2 - Create target system on the new machine (SAP and Oracle installation)

      3 - Perform backup and restore of the database.

      4 - Start the upgrade.
