◆ Migrate()

bool JSON_SETTINGS::Migrate ( )

Migrates the schema of this settings from the version in the file to the latest version.

Schema migration doesn't need to be used every time a setting is added! This is intended to be more of an "escape hatch" in the event that we decide to move settings around or make other changes to a settings file format that can't simply be handled by loading a new default

Returns
