We are currently running SAP PI 7.0 and are required to go to PO 7.4 (dual stack).
The reason for the move is because SAP PI 7.0 goes out of support at the end of this year.
We have about twenty interfaces spread over a handful of third-party systems. Outgoing interfaces tend to be either from ABAP Proxy to SOAP or File. Incoming interfaces tend to be SOAP, File or HTTP to IDoc or ABAP Proxy. Some interfaces use ccPBM.
We have been given two options on doing this:
1. Clone the current environment and perform upgrade from 7.0 to 7.4 on the clone.
1. Fresh installation of 7.4 on a parallel environment and "migrate" the interfaces from 7.0 to 7.4
In both cases, the existing system will be replaced.
If option 1 is done, I presume all the interfaces will appear in 7.4 after the upgrade, but there may be some configuration changes required to the interfaces in 7.4 afterwards?
If option 2 is done, is this done via a migration tool, or is the migration tool only used when going from dual stack to single stack?
If the migration tool isn't an option, I presume we would have to manually export SLD, IR and ID content from 7.0, and import them into SLD, ESR and ID in 7.4?
What tasks would be required once the interfaces are migrated/exported/imported?
I have had a look at the document "Decision Making Factors when Moving to SAP NetWeaver Process Integration 7.3 - Upgrade or New Installation with Phase-out"
