SAP Replatforming

[Former Member]

Hi All,

We are currently have SAP R/3 release 6.4 with Oracle 9i as the backend database and with OS AIX 5.2. We will be now moving on to a shared environment with Oracle 10G and AIX 5.3. How should we proceed to do this copy. Currently we have the applications installed on one lpar and the database on the other. In future we are planning to have them on the same shared env. Can we follow the standard homogeneous system copy procedure.

Thanks in advance

Hi,

if you do R3load, yes it is considered homogeneous copy,

even if the OS/DB release is diffrent. Use the correct

installation kit for 10.2 to install the target.

If you are quite up to date with SAP_BAS Patchlevel on 6.40,

your installation might fail at the very end, because the kernel

from the CDs is too low for a recent SAP_BASIS patch.

You either need to patch the kernel then AND continue the

installation or exchange the SAP-Kernel archives BEFORE

you even start to install.

If you like to go by backup-restore, you'll need to install Oracle 9.2

first to do it according to the book, and do the oracle upgrade right

after that. If the system is not productive, you might decide to

do the 10.2 install and NFS-mount a 9.2 oracle home from somewhere

else, just to finish the recovery and do the upgrade to the freshly installed

10.2 ORACLE_HOME, but you will be on unsupported ground then and

should have done some 9.2->10.2 upgrades already in common

environment.

Hope this helps

Volker
