We are redesigning our Web Service Architecture, and needed to set up ESR. As, we don't have a PI system(HCI will come soon), We have to install NetWeaver CE to set up our ESR.
Now, we are in process to upgrade our NetWeaver from 7.0 to 7.5. Is this going to affect the installation of CE. Do we have to first do the NetWeaver Upgrade and then go for CE.
As we need ESR( To access SPROXY), can we proceed with the CE Installation and SPROXY Connection with ESR and later on continue with the Upgrade processes.
Additionally, can we set up SPROXY in any other way without PI system.
Based on the information provided. I would install a single stack Process Orchestration (Netweaver 7.5 AS Java) for your ESR and BPM. If you are upgrading your ERP 6.0 to EHP6, EHP7, or EHP8, your hub system will need to at least run on 7.31. You can still use a dual stack if you want, but that is not the direction that SAP is heading. PO is the future.
