The Trusted configuration had changed between 11.5 and 11.6. It will have to be redone. It now uses either a DB2 or MySql database. See
Setup Trusted Access.
To migrate the XCOM trusted file from a XCOM V11 system to XCOM V11.6, please follow the instructions below:
1. From V11 export the trusted registry path
Computer\HKEY_LOCAL_MACHINE\Software\ComputerAssociates\XCOM\REMOTESYSTEMTS
2. On V11.6 do an import of the registry file
3. Make sure that you’ve created the database created with the proper tables for Trusted
4. Make sure you can connect to that database
5. Run the XCOMTRST utility.

SETUP TRUSTED ACCESS in the CA XCOM Windows Guide.
