Hi Everybody,
in our company, we are planning to upgrade our SAP ERP systems from version 6.0 Ehp4 on Netweaver 7.0 Ehp1 to Ehp6 on Netweaver 7.0 Ehp3. Our landscape consists of 3 systems (Development - Quality - Productive) and our type of installation is distributed which means we have 3 sap application servers and 3 database servers. All the systems (application servers + database servers) run on RED HAT Linux Enterpise Edition 5.5. Oracle Version is 11.2.0.3 Enterprise Edition.
As I have seen on service.sap.com/pam, SAP ERP 6.0 Ehp6 on Netweaver 7.0 Ehp3 runs with SAP Kernel versions 720EXT-721EXT, that are not supported for RHEL 5.5. So our first step is to upgrade the operating system to RHEL 6. The question is if we can avoid upgrade the operating system of our Database Servers as Oracle 11.2.0.3 is ok and upgrade the O.S of SAP Applications Servers only.
Thank you in advance
