IBM Cognos User Manual page 249

The -y1 option requires that you configure the IBM Cognos Series 7 security on
which the upgraded model was designed as an available namespace in IBM
Cognos. The unique identifier that locates the user class in Access Manager is
converted to an IBM Cognos identifier, and this process will fail if you use this
option with a different Series 7 namespace.
The following example
v runs cogtr.exe in batch mode, does not generate cubes or update categories
v saves the .mdl file
v preserves the IBM Cognos Series 7 user class views and user classes associated
with the IBM Cognos Series 7 model
v logs onto the GO namespace with the Administrator user name and no
password
cogtr.exe -n2 -ox -s -y1GOnamespace=Administrator/ -mNationalV7.mdl
-y2 option
This option imports only the IBM Cognos Series 7 user class views associated with
the upgraded model.
Choose this option when you want to import the IBM Cognos Series 7 user class
views associated with the model, but not the user classes.
This option allows you to maintain the view operations applied in the IBM Cognos
Series 7 user class views but not use a Series 7 namespace with the custom views,
or if you do not intend to expose Series 7 as an a available namespace configured
in IBM Cognos BI.
The following example
v runs cogtr.exe in batch mode
v does not generate cubes or update categories
v saves the .mdl file
v preserves the IBM Cognos Series 7 user class views associated with the IBM
Cognos Series 7 model
cogtr.exe -n2 -ox -s -y2 -mNationalV7.mdl
-y3 option
This option discards the IBM Cognos Series 7 user class views and user classes
associated with the upgraded model.
Choose this option when you plan to create new custom views and use only the
security objects currently configured in the Cognos namespace.
The following example
v runs cogtr.exe in batch mode
v does not generate cubes or update categories
v saves the .mdl file
v discards the IBM Cognos Series 7 user class views and user classes associated
with the upgraded IBM Cognos Series 7 model
cogtr.exe -n2 -ox -s -y3 -mNationalV7.mdl
