Migrating from Cognos ReportNet to Cognos 8

Last week i was trying to upgrade the model and publish a Cognos ReportNet 7.3 FM Model to Cognos 8. When i was trying to achieve that i have faced some issues regarding the installation.

Following things are required to check this example:

1) Cognos ReportNet 7.3 Server and Framework Manager 7.3 installed.
2) Sample Cognos ReportNet FM Model which we are going to upgrade.
3) Cognos 8 Server and FM 8 installed

I created a sample model in FM 7.3 and saved the model for upgradint it. I have opened the model in FM 8 to upgrade it. When i give upgrade model, it will verify the model - when verifying the data sources and security settings need to be similar to Cognos ReportNet server. If those ojects are not available, the we have to create in C8 environment and verify the model. If setup is available, there will be no errors regarding those missing setup. Then we have to makesure all the tables used in model are present and then we have to verify eacn and every object.

Following are some errors when i upgrade the FM model:
