Any impact to the existing interfaces, web services, etc by upgrading the system from 7.0 to 7.1 or 7.3

[Former Member]

Hi,

We are thinking about upgrading our current SAP PI 7.0 to 7.1 or 7.3, just wondering if there are any impact to the existing PI objects, such as interfaces. Would most of the objects (interfaces, webservice, etc) needs to retested after the upgrade?

Really appreciate your input.

Hi Blue,

you have to check adapter compatibility first. list down all adapters you are using and check it's compatibility.

if you are using any java mapping you have to do little change in it as in 7.1 and above different interface is implemented.

if you are going to 7.3 java only then you don't have option to use ccbpm. you need to use SAP NW BPM. you have to change http,idoc adapters also. for xi adapter SOAP adapter will be used.

below doc would be handy to analyse the same.

Hi Muniyappan,

Thank you very much for your reply.

Here are few cents..

Upgrading 7.1 to 7.3 (dual stack) would not have major impact

7.0 runs on 32 bit OS and using jdk 1.4  whereas 7.1 and 7.3 runs on 64 bit OS and jdk version 1.5+

So you will have major impact on mappings UDF/Java, Parser fixings for existing xslt mappings. Jdbc and RFC lookups etc...  You will certainly face some impact.  I see more on the design area - mapping side.Rest will be handled/fixed smooth.

You might want to see this wiki for mapping area.

You have to test everything in PI 7.3 after upgrade, you might face some issues.

Hi Blue,

That depends on the installation which you have currently and the installation that you want to do now.

As suggested by muniyappan, we have to check the adapter compatibility, based upon that we have to prioritize the installation option.

Single stack:

--> CCBPM not supported.

--> Proxies and all the mappings are supported.

Dual stack

--> Dual stack support will be there till 2020.

--> To upgrade to single stack, we only need to do minor changes. no need to do it from the scrap.
