SAP PI 7.1 Dual stack to 7.4 Dual Stack upgrade

Dear Experts,

One of our customers have decided to do an 7.1 PI dual stack to 7.4 dual stack upgrade. We have mentioned them to go for a signal stack migration considering SAP PI future road map but due to time and cost constraints they have decided to take dual stack path.

The current PI landscape is complex in nature as it has 50 BPM's connecting legacy systems and performing 4-5 processes. There are many RFC look ups called to SAP ECC to validate the data and process accordingly. In PI they maintain and update lots of local table for financial data.

I have suggested them to consider this as a migration project which means standing up a new 7.4 dual stack rather than upgrade project and migrate some critical interfaces to test the same and see how it behaves and then go for full fledged migration of all interfaces.

Our client wants to go for in place PI upgrade to reduce the hardware cost. In my experience in-place upgrade for complex PI landscape is cumbersome and lot more effort is needed in fixing the problems which are caused due to upgrade.

My questions start here, In case our clients decide to go for in place upgrade for 7.1 to 7.4 dual stack. Please it would be really appreciated if any one of you can share with me the pain points which needs to be considered apart from the standard checklist of things which are taken into account out during upgrade projects.

Please let me know if you need any specific information to answer my question better.

Thanks in Advance .

Regards

Hari

Unless you consider to redesign the interfaces ( classical to ICo's /use IDOC_AAE adapter/ change proxy communications to use Soap adapter), i don't see any pain points.

In other-words, as long as you are doing just an upgrade without choosing/configuring any of the new features available with the later version, you shouldn't face any issues.

Are you planning to change anything even if you choose dual stack upgrade?

Hareesh-

Thank you very much for your quick response. As of now we will not be modifying the design of existing interfaces. As mentioned before do you thing will there be any impact to the local tables which are maintained in PI. If we are developing new interfaces in future we can still leverage the new functionality of PO dual stack. Is that right?

Please let me know.

Thanks in Advance.

>>> You thing will there be any impact to the local tables which are maintained in PI.

I don't think so.

Yes. you can.

Alert configuration is something that you'll asked to choose during the post installation steps.

Either you can switch to the new component based message alerting or continue to use classical configuration.

However even this can be changed at later point
