DMM has the two options to save configuration.
Either you download the JSON configuration file in the screen that precedes the execution and store it in your file system (a useful solution if you're executing the migration or scrambling process in another application that leverages the DMM DLL) or you can save the configuration directly within the OutSystems DMM component.
Configurations saved through this second option will be manageable by clicking "Management > My Configurations" on the top menu.
When you click on this option, a table containing all the saved configurations will appear and let you choose an action for each:
Edit allows you to change the name of the configuration
Download lets you save the configuration JSON in your file system
Upload allows you to update the configuration with another one from your file system
Use Config to load the specific configuration. When selected, a popup will appears with some options:
Adjust the configuration for a new environment or database.
Validate and load configuration: validate the configuration to identify any mismatch with the environment, then go to the Final Configuration screen and review the settings.
Skip validation: go to the Final Configuration screen and review the configuration.
Delete lets you remove the configuration from the system
