upgrade 4.6C ECC6

[Former Member]

Hello,

I plan to upgrade my R/3 4.6C Oracle 8.1.7 to ECC6 oracle10g.

In all the documentation, SAP doesn't indicate the CPU, the RAM and the disk space required.

Furthermore I have to upgrade oracle version the 10g but I don't know what are the steps (9.2... or directly to 10) nor moment to do this upgrade.

Somebody could help me?

Thanks

Thank you,

But i stil have a question about the upgrade of Oracle.

This is all the steps of a migration:

<b>0. Upgrade Oracle to 9.2.0.7,</b>

1. Steps in ABAP Preparation System (>Web AS 6.10),

2. Upgrade: PREPARE and Tool Import (R/3 4.6C),

3. Unicode Preconversion (R/3 4.6C),

4. Database check (R/3 4.6C),

5. Upgrade,

<b>5'. Upgrade Oracle to 10g,</b>

6. Additional Preparation Steps in SAP ECC non-UC (SAP ECC),

7. Unicode Conversion Phase,

8. Unicode Conversion Completion (SAP ECC).

Are the two steps 0 and 5' at the correct time for the migration??

Thanks for your help.

Hi,

Step five will come after database check (point: 4) SAP upgrade will be the next part.

or you can also upgrade to 10g before prepare (use 46D_EXT entended kernel)

thanks

Hi,

You can refer to below mentioned notes for resource requirment:

778774 --> Resource requirements for ECC 5.0

752532 --> Resource requirements for R/3 Enterprise 4.70 x 2.00

517085 --> Resource requirements for R/3 Enterprise 4.70 x 1.10

For oracle upgrade u need first upgrade to 9.2.0 and then perform upgrade to 10g

Direct upgrade to 10g is not tested and validated but its is possible, If you intend to perform a direct upgrade from Oracle 8.1.7 to Oracle 10.2, see the Oracle Database 10g Release 2 (10.2) upgrade documentation.

www.oracle.com/technology.

hope this helps u out.

thanks

Uday.
