Hello,

Our customer wants to change their operating system from HP UNIX  to LINUX 
 that SAP R/3 works on. Their current configuration shown below.

        HP-UX Rel. 11.00  ( 64-bit )
        Oracle RDBMS Rel. 8.0.6.00  ( 64-bit )
        SAP R/3 Rel. 4.0B   ( 64-bit )

Future configuration will be:

        Linux Red Hat AS Rel. 3.0 Update 2   ( 32-bit )
        Oracle RDBMS Rel. 9.2  ( 32-bit )
        SAP R/3 Rel. 4.7   ( 32-bit )

We examine all restrictions and define a road map for this upgrade - 
migration process. Our action plan is shown below:


-1-     Upgrade Oracle database version  from 8.0.6 (64 bit)  to 8.1.7(64 
bit) 
-2-     Change  Oracle database wordsize from 64 bit to 32 bit
-3-     Migrate r/3 & database from operating system HP-UX Rel. 11.00  ( 
64-bit ) to Linux Red Hat AS Rel. 3.0 Update 2   ( 32-bit )
-4-     Upgrade Oracle database version  from 8.1.7 (32 bit)  to 9.0.2(32 
bit) 
-5-     Upgrade sap r/3 version from 4.0B to 4.7 Enterprise Edition


But we seen there is a restriction to migrate Linux Red Hat  with SAP R/3 
4.0B. Your internet site recommends SUSE Linux Enterprise server 8.

Please examine our  steps, and if you have any suggestions share with us.

Best regards
