SAP ERP 6.0 EHP4 upgrade from SAP R/3 4.7 1.10

Question

Dear Experts,
Our client is going to upgrade current landscape SAP R/3 4.7 1.10 to ERP 6.0 EHP4. The Source system O/s is AIX 5.3 and database is db2 8.1. Client procuring new hardware for the target release ERP 6.0 landscape and the O/s is going to be AIX 7.1 and databse would be db2 9.7 FP3.
As part of the upgrade we are going to do initial upgrade in the mock server and vendor is going to provide mock server with AIX 7.1 O/S.  Current database size is 100GB, hence we are going to copy the production server data into the mock server using export and import method,
Here my doubt is can i install db9.7 directly and do the import (using compitable kernel)?, insteady of installing source database version 8.1 and later upgrading to db2 9.7 . Please clarify me whether can i go head and install the db2 9.7 and do the system copy using R3load.
Thanks and Regards,
Seshu

Hello,
You can go ahead for IMPORT with DB 9.7.
We completed an OS/DB Migration Project (which involves system copy using EXPORT/IMPORT) and we utilized direct newer version of DB2 on the target during IMPORT.
But please confirm whether the kernel of your release would work fine with DB 9.7 or not. Otherwise, there is no problem in going for higher version of DB2 here.
Small question -  Why you want to test the Mock Upgrade on DB2 version which is different than the current version on production server ? Or are you planning to upgrade your current DB2 8 to DB2 9.7 BEFORE the SAP Upgrade on all the servers - then the testing is OK I think (however OS is still the different - Or may be you will go for system copies for this too !)
Thanks
