Can the Target Version Be Earlier Than the Source Version?

Updated at: Jul 31, 2019 GMT+08:00

Software/Firmware can be rolled back from a later version to an earlier version. The IoT platform checks whether the target version is the same as the source version. If they are consistent, the message "The current version is the same as the target version" is displayed, and the IoT platform does not initiate a rollback. If they are inconsistent, the IoT platform starts a rollback.
