Hello Markus,

Apologies, you are correct. I was confused with the Migration Check service which is only mandatory for a system which is going to be in productive use.

Hello Ravi,

A certified consultant is only a requirement for an migration of a productive system. You should review the heterogeneous system copy guide

A heterogeneosu system copy will require a migration key, you must request this at

Oh - this is interesting! The website says:

If you want full support for the migration (be it a production system or not)
then you must secure the services of a technical consultant 
with special certification for OS/DB migration.

Hi Markus can you tell me where this

"If you want full support for the migration (be it a production system or not)

then you must secure the services of a technical consultant

with special certification for OS/DB migration."

is written?

Thanks

Thanks very much for that as I was wondering if we were copying from one set of hardware to another same OS and DB, then this does not need to be covered by the restrictions of the "migration" - do you agreen

I looked in the FAQ (in the paragraph you pointed out and there is this

*What is a homogeneous system copy?*

A system copy that doesn't involve the change of either OS or DB is called a homogeneous system copy. It is not covered by this subject and the restrictions of a migration don't apply. To change from 32 bit to 64 bit is also a homogeneous system copy.

Do you agree?

Thanks

yes - because then it´s a normal "systemcopy".

This is a heterogeneous system copy.

please provide your expert guidelines.

Since it´s a heterogeneous copy you need to have a certified migration consultant on-site, otherwise you will loose support for the target system (see the FAQ at http://service.sap.com/osdbmigration).

Database is Oracle 10.2.0.2 .(only need to change the os not database)

I´d use the R3load method. This will give you a "free reorganization". There are however other ways of doing that (transportable tablespaces).

Be aware that Solaris on SPARC is a BigEndian platform whereas Linux is implemented as LittleEndian - so if you exchange binary data with other systems they need to be aware of that fact.
