Latest firmware might not be applied directly due to pivot firmwaresBy "pivot firmware", we define firmware versions that are mandatory to upgrade to before going any higher. In fact, all major versions (v12.0s0, v13.0s0, ...) are pivot firmwares. For example: if the firmware version is currently 12.3s0 and there's a wish to upgrade to v14, a first upgrade to v13 is required. Once the current firmware version is 13, then only can the upgrade to v14 be operated.
. In such a case you might need to update a Flexy several times.
