We are in the middle of testing exporting / importing the Content Store to the latest version of Cognos i.e.
11.0.11 to 11.1.7 Interim Fix 3
In a brand new Content Store while doing the import we select the following options:
Upgrade all report specifications to the latest version
Do not assign new IDs during import
All our Cognos objects seem to be exported correctly. However one report which we use for performance testing is erroring in the new version.
In the stacktrace I notice the following line
Caused by: java.lang.ClassCastException: com.cognos.xqe.runtree.relational.XSetFunction incompatible with com.cognos.xqe.runtree.relational.XExpression
We wanted to reach out to see if you had any additional insights into this error.
