ECC6.0 Ehp3 - System Copy Solaris to Windows

Hi,

We are planning to prepare a Sandbox (Test System) with Production System Data. Since the OS is differing we have opt for hetrogenous system copy method.

Source System(Production): Solaris 10/Oracle (NW SP17 and ECC 6.0 with Ehp3(DIMP, SAP-APPL and EA-APPL)

Target System(Sandbox) : Windows 2K3/Oracle

We have the Sapinst of BS2005 SR3 only and also we got the following queries

1. Since we are having Ehp3 in source system, is there any impact while doing the system copy?

2. How to prepare the target system with same patch level of SAP software components as our source system

Regards,

Thahir

    You can't do the system copy as "I install a new system and overwrite the database".

    There are a few points to consider:

    a) a heterogeneous system copy requires a certified migration consultant on-site, otherwise you'll loose support for problems during the migration and for the target system (see http://service.sap.com/osdbmigration and Hinweis 82478 - SAP System OS/DB Migration).

    b) the only supported way of doing such a migration is using R3load as the tool of choice. You'll have to start sapinst on the source system, export your database and import it into the target system

    c) direct database copies are not possible (Solaris SPARC is a BigEndian platform, Windows is LIttleEndian, Windows won't be able to open the files created by Solaris)

    • Markus/Martin,

      You are right, export contatin the same structure and whole content of database. Just we faced some minor issues like kernel & java starting issues which we are fixed up.

      We prepared the system and released to the testing team 😊

      Thanks for your response...
