scenarios to migrate OS and DB versions

[hassan_mourtadi]

Hi all,

To migrate the perating system (redhat linux 4.5 to 6.x) and database (Oracle 10.2.0.2 to 11g), what are the possible scenarios  and  considerations  to be taken to achieve the migration?

knowing that:

1 - the version of SAP System Landscape SAP ECC is  6.0 NUC with the following levels of SP:

SAP_BASIS    700     0011 SAPKB70011

SAP_ABA       700     0011 SAPKA70011

ST-PI 0005      2005_1_700 SAPKITLQI5

PI_BASIS        2006_1_700 0001 SAPKIPYM01

SAP_BW         700    0012 SAPKW70012

SAP_AP          700    0008 SAPKNA7008

SAP_APPL     600     0009 SAPKH60009

SAP_HR         600     0018 SAPKE60018

SAP Kernel version is 150

2 - The second landscape used and connected to SAP ECC 6.0 is SAP NetWeaver BI 7.0 (ABAP / JAVA).

Thank you in advance.

Hello,

What about the sp and oracle versions?

Have you read the Oracle upgrade guide ?

You may read that and it has all the information.

Like I said before, first get the system on RHEL 6 and then install Oracle 11G.

The SP level is not a problem but yo need to use a supported kernel for the SAP system.

Hello,

The 7.20 kernel can be used with the current level of SP?

Yes

Support Pack (SP) doesn't matter and as per PAM RHEL is supported platform for Oracle 10.2.0.2 and 11g too.

Hello

First check PAM for supported combination.

https://service.sap.com/sap/support/pam?hash=pvnr%3D01200615320900001296%26pt%3Dt%257CPLTFRM%26ainst...

First upgrade the OS to RHEL 6.

You need to also make sure all the required Linux RPMS are installed for the 11G installation.

Oracle® Database

http://docs.oracle.com/cd/E11882_01/install.112/e24321/pre_install.htm#LADBI1085

Once the OS has been upgraded upgrade the Oracle database to 11G.

To upgrade the database to 11G refer this upgrade guide.

Hello and thank you for your reply,

The OS migration can be done in place: (redhat linux 4.5 to 6.x)?

Yes,I think you can do it.

Refer PAM.

Upgrading from a previous Red Hat Enterprise Linux release to RHEL 6

Red Hat does not support in-place upgrades from one major RHEL release (e.g. RHEL 5) to RHEL6 (see https://access.redhat.com/knowledge/solutions/21964). The only supported option to upgrade from an older RHEL release to RHEL 6 is to backup all data on the system, install and configure RHEL 6 on the server and then reinstall the applications and restore the data from backup.

Hi RB,

What will be the problem in migration from 4.5 to 6 from SAP's point of view ?

It is not SAP, it is Red Hat who does not support this upgrade.

I agree with Reagan and have done the same in our landscape.
