Recommended installation option PO vs. AEX / adding usage type in future

[Former Member]

Dear guys,

at the moment some clients I am working with a thinking of migrate their existing PI dual stack landscape and setupt a new single stack landscape.

Doing so there is the question either to go for PO or AEX.

Often there is no need for BPM/BRM component yet, but maybe this will change in future.

Therefore there is the question if it is pssible to add BPM/BRM functionality to an existing AEX installation (SID) or not.

So far I found inconsistent information regarding this question.

In this blog it is mentioned that adding of BPM/BRM is not possible.

Instead this presenation indicates that it should be possible to add new usage type to an existing AEX (slide 5 which is also included in Teched presenations)

Can anyone clear up this topic?

Appreciate your help.

Best regards

Jochen

Hi Hareesh

thanks for your reply and pointing me to this thread.

Obviously the deployment possibility changed overtime and was initially not possible but now it seems to be possible.

Process Orchestration - SAP Library

You can obtain Process Orchestration by installation or by adding the corresponding usage types to an existing SAP NetWeaver system. For latter, both are supported, deployment of BPM on an existing AEX system and deployment of an AEX on an existing BPM system.

Also the lately published PO Roadmap indicates that it should be possible to add usage type. (page 25)

Hello Jochen,

Technically, the answer is "yes": it is possible to upgrade AEX 7.31 to PO 7.31 by installing additional usage type BPM on top of existing installation of AEX. This is supported and explained in the SAP Note 1868764 and in the document .

But, on the other hand, the licensing question matters here. Even though such an upgrade is possible technically, the answer to your question will highly depend on license model that is used for AEX (CPU based or volume based) - and this is what William refers to in his blog. This kind of question (like currently utilized license model for your AEX installation and, in case of necessity, possibilities of licence conversion to PO) can be discussed and clarified with an account executive.

Regards,

Vadim
