It is not recommended to upload a database or configuration from the system with a higher version to the system with a lower version. To do this, you need to first upgrade the system with a lower version to the version matching the system with the higher version you are uploading. And, to get the upgraded version, please contact TelcoBrideges support (support@telcobridges.com).
Also, please follow the TBwiki link for migrating the current database: https://docs.telcobridges.com/tbwiki/Migrate_current_database
