Greetings,
Actually you don't have to delete existing models to update the Model Type. Once you have made the SysOID mapping change in the Device Certification utility, and saved the changes to the SSdb database, you can use the NewMM.pl script to update the existing models to the new Model Type. The steps are documented in the "Certification" document, under the section named "Change the Model Type for a Single Device Type Using a Script" (see https://docops.ca.com/ca-spectrum/10-2-2/en/managing-network/certifications/customizing-identification-with-device-certification/change-the-model-type-for-a-single-device-type-using-a-script)
To use the NewMM.pl script to update existing models:
1. Verify the SpectroSERVER is running on the landscape that you want to update the models on. If you are running a Distributes SpectroSERVER environment, you will need to run the NewMM.pl script on each of your landscapes.
2. Open a command line (Linux/Solaris) or 'bash -login' shell (Windows) on the MLS SpectroSERVER, or the Target SpectroSERVER, as the Spectrum owner account.
3. Change directories to the $SPECROOT/Install-Tools/PostInstall directory.
4. Run the following command: ./NewMM.pl -m
The -m option tells the script that it will run a specific model criteria that you will provide.
5. Enter the host name or IP Address of the VNM (SpectroSERVER) you want the script to connect to.
6. Enter the landscape Handle of the VNM in HEX.
7. Enter the System Object ID you want the script to search for.
8. Enter the current model type you want the script to search for.
9. Enter the new Model Type you want Spectrum to use in the conversion. The script will create a log file detailing the results of the conversion. The log file name will in the format of NewMM_Log_<date>. Review the log to ensure all models found were converted.
For Example, using the scenario described in the previous threads:
Once the models are updated to their new Model Type, it's a good idea to run a reconfiguration against the update model types. This will cause Spectrum to re-walk the devices and update the child application models supported by the new model type.
I hope this was helpful,
