system copy 32/64 bits

[Former Member]

My customer is running on Linux Red Hat EL4/IA32 with Oracle 9.2.0 and wants to migrate to a 64 bits system running Linux Red Hat EL4/x86_64 with Oracle 10g release 2.

The sap version they are running is SAP R/3 Enterprise 47x200.

Can I do a homogeneous system copy with the R3load procedure (DB export) and use this export with the installation using the target I described above? Will Oracle be automatically migrated to 64 bits? Can I do an export from release 9 and import it in release 10?

Thanks in advance for your answer. Points will be rewarded.

Kind regards,

Dave Arends

a) imho YES...since you're using r3load the export will be independent regarding database and/or operating system (sapnote 547.314 also states that if os and db remain the same - and only the bit setting differs - sap stills consideres this a homogeneous copy!)

b) yes, you can use this export dump from oracle 9.2 to build the import db on 10.2 (plz read sapnote 940.749)

-> you're running on kernel 6.40?

Hi Andreas,

Thanks for your quick reply. These answers are really helpfull.

The note you mentioned (940749) is not the correct one I suppose since this note is something about CRM. Please can you give me the correct note number.

We are indeed running on a non-unicode 6.40 kernel at this moment.

I saw in SAP note 969519 I can download a master dvd called "DVD Installation Master 6.20/6.40 09/06" which I can use to install the SAP R3E 4.7 Extension Set 2 SR1 on my new 64 bits server. Do you have any experience with such an installation I have to do soon? If so, did you ran into any kind of problems?

Thanks in advance for your reply.

Kind regards,

you can also upgrade your original system to 10g 32-bit... then move database files over to new machine, it will read the old 10g 32-bit database with 64-bit binaries
