The correct way to upgrade a SAP

[albert_vivesleal]

We are trying to upgrade an old system with :

SAP 4.6C

Oracle 9.2.0.4

HP-UX 11.23

to a new (test) system with

HP-UX 11.23

Oracle 10.2.0.2.

SAP ECC 6.0

The correct way seems to be performing an homogeneous system copy from old to new.

Now, the question is .....

Is it possible to perform an homogeneous system copy with different versions of Oracle ?

Is it necessary the Oracle versions are the same ?

Or .... There it exist a procedure to perform an homogeneous system copy to a higher version ?.

Performing directly the HSC from 9.2 to 10.2.will save us a lot of time.

Thank you.

Hi Albe

did you already check the Upgrade Guide SAP ERP Central Component 6.0 SR3 ABAP - unix, Oracle?

(see service.sap.com/erp-inst)

Dear Andreas :

I am working with the SR2 version, and so "Upgrade Guide SAP ERP Central Component 6.0 SR2 ABAP - unix, Oracle".

I have performed 3 succesful upgrades in test mode.

The only thing we want to know is if it's possible to perform an homogeneous system copy from the old system in Oracle 9.2 to new system in Oracle 10.2 .

The steps should be :

- Backup the OLD system in 4.6C Oracle 9.20

- Install SAP 4,6C R3SETUP -f DBR3CP.R3S

- At the point of Oracle installation I will install the 10.2 instead of the 9.2

- Later (if possible) Homogeneous system copy restoring a OLD system Backup over the Oracle 10.2.

- PREPARE

- SAPup

This will avoid us 11 hours of run time.

Danke.

Albert.

Hi Abert,

The scenario what you want may be possible. Let me brief you about how it can be done if your source system is R/3 4.7.

The steps would be :

• Export the OLD system in 4.7 Oracle 9.20 using SAPINST tool (Export database)

• Install SAP 4.7 Using Export dvd created in first step (NO Backup - Restore)

• install oracle the 10.2 instead of the 9.2

(At the end of this steps you will have your system with Oracle 10.2 database)

• PREPARE

• SAPup

So, in short you need to do system copy using SAPINST tool if you want to avoid Oracle upgrade steps.

Now, you need to find out whether you can use R3SETUP for doing system copy. If yes, you can go ahead with above steps.

Hope this helps.

Install SAP 4,6C R3SETUP -f DBR3CP.R3S

At the point of Oracle installation I will install the 10.2 instead of the 9.2

I met problem in windows then I installed 10.2 directly. You can do by this step if possible:

1. Upgrade the oracle fron 9.2.0 to 10.2 in your 4.6C system

2. Install SAP 4,6C R3SETUP -f DBR3CP.R3S

3. At the point of Oracle installation install the 9.2

4. Upgrade the oracle software from 9.2 to 10.2

5. Copy data files from OLD system to this system, rebuild the oracle system

6. PREPARE

7. SAPup
