This information applies regardless of the version from which you are upgrading.
For segmented projects, segments are automatically upgraded when the master project is opened.
You must upgrade a linked project before upgrading any projects that use the linked project.
If a segmented project does not upgrade automatically, follow this process:
Open each segment as a separate project, starting with the lowest level segment in the hierarchy.
Follow the steps to upgrade the model from IBM Cognos ReportNet Model Upgrade or IBM Cognos 8.1 or 8.2 Model Upgrade. Do not repair the segment.
After the upgrade is complete, save the project.
Upgrade each segment in the hierarchy, working back to the main project.
Repair the complete model in the master project.
After upgrading the master project, check in each segment and then check in the master project.
