Connections removed after using Spectrum Modeling Gateway to consolidate older Spectrum versions into one newer Spectrum version

Issue:
The dbsavefile.SSdb method was used to migrate one older Spectrum version to a newer version. Then the Modeling Gateway was used to export another older database of the same version and import it into the same newer database. After running the Modeling Gateway import, connections to existing models from the migrated database are removed.
Cause:
The older database where the Modeling Gateway was used to export the database has some of the same device models as the older database that was migrated using the dbsavefile.SSdb method. Although the same device is modeled in these two different databases, they have different connections. So when the Modeling Gateway is used to import into the migrated database, the connections defined in the import file are used causing existing connections to be removed.
Resolution:
The Modeling Gateway import is functioning as designed creating the connections as they are defined in the import file. The user needs to decide which connections are the correct ones for the consolidation of the databases. 

If the connections from the imported database are the correct connections, nothing needs to be done after the import.

If the connections from the migrated database are the correct connections, then these duplicate device models should be deleted from the older database prior to running the Modeling Gateway export.
