We will change from legacy R10.2.1 to huge Landscape running R10.2.3.
Therefore we have to use the modelinggateway for export the models and import them to the new server as the "model-handles" are not compatible (doing a "models-only" load via SSdbload does not work). In addition, the target was also to get all created connections re-created in the new SpectroSERVER runtime.
After importing with modelinggateway the DialUpLink models have no Primary Interface associations. The missing association is "Is_Backup_For".
This applies to all supported CA Spectrum platforms.
