Hi Experts,
There is a proposal for upgrading PI from 7.11 to 7.31. I have not worked in upgradation project before. So can anyone please tell me what is the role of a PI developer and what are the activities that i need to do?

Hi Lavanya,
After upgrade you have to do readiness check in PI system.
1. Check JAVA stack status by executing sxmb_ifr tcode
2. Check HTTP and RFC connections using sm59 tcode
3. Test the HTTP services using SICF tcode
4. Test SLD connections by executing SLDCHECK tcode.
5. Test connectivity of ESR by executing sproxy tcode in PI
6. Test connectivity between ID and ESR
7. Test connectivity between ESR and SLD
8. Adapter monitoring- Communication channels
9. Check Queue registration
10. Check Cache connectivity
11. Check Delete and Archive Background Jobs
12. Check parameters of Integration engine using sxmb_adm tcode
13. Check for Alerts.
It would be better if you take screen shots of all above mentioned activities before PI system upgrade and also take screen shots of all communication channels parameters.

Thank you everyone for your replies. It is planned to have dual stack only.
Currently, basic adapters are being used for scenarios. And there is one BPM scenario present.
So, once the upgrade is done, should anything additional be done for BPM scenario or can it be handled like other interfaces?
Will the upgrade happen one by one in the landscape?

Apart from what mentioned by KRUPA RAO, I would like to put a point that role of PI developer varies if its not inplace upgrade. In that case it would be migration. But yes that should be only in the case if you are going for a single stack.
But in inplace upgrade you need to find out the scope of optimization and may need to put effort on tunning of mappings and redesigning.
@Krupa: Nice "collection of activities"...

Hi Lavanya,
Recently I have worked on one of the upgrade project from PI 7.1 to 7.31 dual stack .As per my experience below are sufficient.
After BASIS handovers system to PI team .(Usually BASIS will do the upgrade by increasing the patch level.In this approach there wont be much issues post upgrade)
1)Perform health checks as above said .
2)Thorough interface level pipe cleaning(testing) ****(Each interface level thorough testing). Fixing the issues if any .
We faced very few issues like couple of modules didn't worked as expected redeployed once again then started working .
Couple of connectivity issues.
Regards
Venkat

Hi .... in simple words, except developing interfaces right from scratch you need to do all the other acitivites that you do in developing projects. Here you need to migrate interfaces to ensure the business functionality works as before. you may need to re-design interfaces in some cases.

Hi,
you have to do some activities like stopping channels,deregistering queues,releasing transports etc before the upgrade.
for more you can check this note 817920
