Is it possible to upgrade only NW stack without upgrading PI?

Dear all,

We are currently on SAP PI 7.1 EhP1 with Netweaver 7.11 SP10.

As a prerequisite fpr an ECC Uprgade to EhP7, SAP says " When using SAP Portal, SAP BW or PI in conjunction with ERP 6.0 EHP7, the underlying Netweaver version of these systems must be NW 7.30 or higher before upgrading to ERP 6.0 EHP7"

Is it possible to upgrade only the NW stack to NW 7.3 or 7.4 without upgrading SAP PI to 7.3 (or SAP portal or SAP BW to the next available version) ?

Thanks and Regards,

Reena

Hello Reena,

The official recommendation from SAP is that the PI system must be on the highest release in the landscape. See note 1043047 Compatibility of XI/PI in the system landscape. So the recommendation is to upgrade your PI first and then upgrade ECC.

However, some customers have successfully upgraded ECC first. Several issues were encountered. These are documented in note 1942289 Known issues with PI and ECC EHP upgrades

Regards
Mark
