Officially you have to register your OS/DB migration at SAP and after signing the migration service contract, SAP will send you the software.. However, you can just download the software from the marketplace. It's the same kit.

Hi Mark,
Some more help please. my boss asking me to do upgrade of the database and OS migration at the same. is it posible and ok to do. please have a detail below
Source system CRM 5.0
OS : Sun Solaris 10
DB : DB2 8.2 Fix Pack 13
Stack: dual
DB& Instance : database and central instance in single host.
kernel version ::Release 700 and patch 146
Target System CRM 5.0
Databases OS : AIX 6.1 for ABAP stack and JAVA Stack but different hosts for two different database
CI OS : RHEL 5.3 for ABAP and Java Stack
Database : DB2 9.5
Stack : dual
DB host name : <DB1>
ABAP stack host name: <ABAP1>
JAVA Stack host name:<JAVA1>
What we are trying to do is
We want split the dual stack system and put the each single Stacks into different hosts. We are keeping databases( ABAP database and JAVA database) in AIX 6.1 and CI of ABAP and JAVA in RHEL 5.3
I have the following doubts and please clear me
1. Do we can Split the stacks at the same time while doing OS Migration? ( and Splitting Stacks will going keep into Different hosts)
2. If we split the Stacks into different hosts then do we have any problems in CRM system
3. If we get any issues then SAP will support and do you have any SAP recommended documents to separate the ABA and JAVA Stacks or SAP will not Support?
4. Do we can do database upgrade While doing the OS migration (like export DB2 8.2(sun) to import DB2 9.5(AIX)) and if yes Is advisable to do like that?
I am very much happy to Answer your call @ 732 925 6974
Thank you
Hi Vswanadha,
1. Do we can Split the stacks at the same time while doing OS Migration? ( and Splitting Stacks will going keep into Different hosts)
Technically this is possible, but I don't know if it is supported by the standard way of a heterogeneous system copy.
2. If we split the Stacks into different hosts then do we have any problems in CRM system
No, you shouldn't. Check the following link for this. Only for PI and MI systems, a dual stack is mandatory.
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/d074d7de-8d55-2b10-1e94-fb2e9d2893d1
3. If we get any issues then SAP will support and do you have any SAP recommended documents to separate the ABA and JAVA Stacks or SAP will not Support?
If the configuration and the way to get it is supported by SAP, you don't have any problems. So the seperation of the CRM stack is supported, however I don't know if it can be done in one step during your heterogeneous system copy. You might have to copy your system twice, so copy the dual stack system twice and remove the ABAP stack on the one site and the java stack on the other site afterwards.
4. Do we can do database upgrade While doing the OS migration (like export DB2 8.2(sun) to import DB2 9.5(AIX)) and if yes Is advisable to do like that?
I know this can be done for Oracle (homogeneous system copy), so I can imagine that it is possible for DB2 as well. Since I don't have DB2 knowledge, I cannot answer this question regarding this subject.
Before you can start your migration, you have to fill in a questionnaire at SAP. If you mention your strategy above you know directly if it is supported by SAP.
You can also buy some remote consulting hours at SAP for all your questions.
Some additional info:
Note 547314 - FAQ: System Copy procedure
Note 82478 - SAP system OS/DB migration
Kind regards,
Mark
Have you checked heterogeneous system copy guide ?
Also, for migration, you need migration certified person onsite. Also, you will need migration key from SAP.
Thanks
Sunny
