IED Configuration Migration (ICM) migrates the configuration from an old relay product version into the latest product version with the corresponding functionality. The configuration migration is done by the Migrate Configuration functionality in PCM600. IED Configuration Migration retains the contents of an existing IED configuration and enables using it with the latest product version.
The newer product versions and the function revisions have been designed to be backward compatible. No functionality is removed in newer function revisions apart from some exceptions.
