Solaris Sparc to x86 for Intel - is a migration?

[Former Member]

Hello everyone,

We would like to switch our existing servers from Solaris Sparc to Solaris x86 for intel. We have Oracle 11 running and SAP ERP 6 Systems (some with EHP5, EHP6 and a few with ERP6).

Is this an OS Migration from SAP point of view?

Best Regards

Hi Arun,

This is a Heterogenous migration from x_64 to Intel architecture. For this you may need to follow the steps required for heterogenous system copy.

Reason being: x_64 has different codepage ( big endian) while Intel Architecture has different codepage (little endian).

Hope this helps.

Thanks Deepak, that helps.

Appretiate your quick reply!

This is incorrect, even though this migration require a full export/import is considered a homogeneous system copy as nor the OS or the DB change. Only the Hardware arquitecture is changing.

Here a previous discussion about it.

Hi Juan,

There is a contradictory response in another thread which says it is hetergenous system copy.

Hi Juan,

There is one more thread from Markus Doehr where he mentions its hetergenous system copy.

Hope this clears the confusion.

Because of the change in Architecture the migration need to be done using R3load method (impor/export),  Same procedure as a Heterogeneous system copy, but because theres no change in OS/DB the copy is considered a Homogeneous System Copy.

Hi Juan,

Since there is a change in codepage it is treated as Heterogenous migration and not homogenous migration.

Even you have mentioned it as heterogenous in the thread https://scn.sap.com/thread/3143678

Yes, I believed it was that way, but change in endianness (and so code page) does not make a migration heterogenous. This particular scenario is discussed during the OS/DB migration certification course.

Thanks to both of you for all the info!

I found this blog http://blog.ranadive.net/2012/12/homogeneous-systemcopy-or-heterogeneous.html

And this answer my question

Have a nice day!

If you are asking this from the point of view of knowing if you need a migration certified consultant to perform it, then the answer is no, you don't.

We have just gone through this very migration ourselves, and carried out the process entirely with in-house, non-certified, staff, with SAP's blessing.
