scm migrator is a tool that can be used to migrate indicators from one appliance to another. It may fail if there are existing values on the appliance.
The "non-standard SSH" indicator fails to import with an error that it already exists.
Error seen on the CLI:
1- Use Backup/Restore via the web GUI to backup the configuration including indicators and restore it to your second appliance. See the following documentation on how to perform these steps:
Backup and Restore
2- Contact technical support to delete the duplicated row.
