Hello Experts,

We are in the ECC 6.0 EHP7 version of SAP ERP and we are planning of migrating to the SAP HANA database. Our machine is an IBM Power 7, with OS / 400 V7R1.

In the SAP site(Matrix), I have located for version EHP7 for SAP ERP 6.0, there are SAP Kernel and SAP HANNA Database for my version of the operating system. Has anyone migrated the DB / 400 database to SAP HANA and is still running OS / 400 V7R1 or V7R2 in the production environment?

You can help me with your experience.

Yours sincerely,

Marcelo P. Silva

Hi Marcelo,

I cannot give you any feedback from practical experience, but I have two remarks:

  1. The SAP HANA database is always running with the operating system Linux - either on Power hardware or on Intel (or compatible) hardware. The application server(s) for the HANA database can run on IBM i 7.1 or higher (SAP NetWeaver 7.40) or IBM i 7.2 or higher (SAP NetWeaver 7.5).
  2. If you want to run the SAP HANA database in a Power platform, SAP requires a minimum hardware level of Power8 for productive use. In a test environment, you can use Power7+, but Power7 is not supported with HANA.

Kind regards,

Christian Bartels.

Hi Marcelo,

to answer your question easily - yes, you can use the IBM i 7.1 as primary application server (PAS) or additional application server (AAS) like already explained by Christian. This will be used in every migration with SUM DMO. Therefore the kernel and the operating system must be supported to connect to the HANA DB.

Usually the target system will be fresh installed on new hardware and also used for PAS/AAS. Also linux will be used for the whole system to get a homogenous system for a harmonized support cycle and the resulting maintenance.

I have already successfully migrated some IBM i systems to HANA. A few things have to be consired like on every platform, but it works.

Regards,

Jens
