OS/DB migration from IBM zOS to IBM AIX for R/3 Enterprise 4.7 x 100

44 Views

An OS/DB migration is required from zOS to AIX for R/3 Enterprise 4.7 x 100.

By default, R/3 4.71 is using kernel 6.2. But SAP stops the maintenance for kernel 6.20 and kernel 6.40 (or 6.40_ext, or 6.40_ex2) is recommended.

My question is which CD (include 6.20 kernel) will be used for export and import?

Under https://service.sap.com/swdc --> Installations and Upgrades --> My Company's Application Components" SAP R/3 ENTERPRISE" SAP R/3 ENTERPRISE 47X110 --> Installation --> OS , I can find:

CD R3E 4.70 SR1 (U) SAPINST DB2 UNIX/NT

CD R3E 4.70 SR1 (U) Kernel DB2/UDB A,L,N

and I believe they are 6.20 version. There is no 6.40 kernel there.

Note 664679 (Installing 6.40 kernel in SAP WEB AS 6.10/6.20) describes a way to upgrade the kernel to 6.40. It does not apply to a fresh installation.

Migration requies the latest R3LDCTL, R3SZCHK, R3load for both export and import.

Under https://service.sap.com/swdc -->Support Packages and Patches --> My Company's Application Components" --> SAP R/3 ENTERPRISE --> " SAP R/3 ENTERPRISE 47X110" --> Entry by Component" --> SAP R/3 Enterprise Server, we can find:

  1. SAP KERNEL 6.20 32-BIT (no longer in maintenance)

  2. SAP KERNEL 6.20 32-BIT UNICODE (no longer in maintenance)

  3. SAP KERNEL 6.20 64-BIT (no longer in maintenance)

  4. SAP KERNEL 6.20 64-BIT UNICODE (no longer in maintenance)

  5. SAP KERNEL 6.40 32-BIT

  6. SAP KERNEL 6.40 32-BIT UNICODE

  7. SAP KERNEL 6.40 64-BIT

  8. SAP KERNEL 6.40 64-BIT UNICODE

  9. SAP KERNEL 6.40_EX2 32-BIT

  10. SAP KERNEL 6.40_EX2 32-BIT UC

  11. SAP KERNEL 6.40_EX2 64-BIT

  12. SAP KERNEL 6.40_EX2 64-BIT UC

The version of R3LDCTL, R3SZCHK, R3load under kernel 6.20 is quite old. So I think 6.40 is recommend to work with those migration tools.

Per note 971646, there is an DVD (Material Number 51033746) "6.20/6.40 based products Installation Master (Edition May 2008)" but it only apply to Enterprise 4.7 x 200, not Enterprise 4.7 x 100.

So who can clarify which CD I can use for this migation?

Thanks,

James
