Troubleshooting
Problem
Sometimes it becomes desirable to move a report into an environment of a previous vesion of Cognos. This can sometimes be done without having to re-create the entire report.
Resolving The Problem
It is not possible to downgrade a Cognos 10.x report to a Cognos 8.x version, but you can downgrade a Cognos 10.x report to a lower version of Cognos 10
Cognos 10.x
If you copy a report spec to the clipboard and look at it in a text or XML editor, you will see it starts like this:
<report xmlns="http://developer.cognos.com/schemas/report/11.0/"...
The 11.0 is the version of the report schema. Usually all that is needed to downgrade a Cognos 10 report is is to change the report schema version number. Then the modified report can be copied to the clipboard and opened in a Report Studio instance launched from an older version of Cognos 10.
Here is the mapping of report spec versions to Cognos BI server versions:
11.0 - Cognos 10.2.1 (Fix Pack 1 or above)
10.0 - Cognos 10.2.1 (no Fix Pack)
9.0 - Cognos 10.1.1
8,0 -Cognos 10.1.0
