Different dataplane firmware version after replacing SCG200 in a cluster
We have clustered two SCG 200 and due to a failure in a dataplane we have replace the faulty unit to a new SCG200. After integrating the new device with working SCG ( before replace the new device firmware has upgrade to compatible with the existing SCG) we see the dataplane firmware is different with the existing SCG. New SCG dataplane firmware version is lower than the older SCG dataplane. Need to know why there is a difference?
Command show version output same version in both SCGs, but under cluster planes it shows different firmware versions in dataplane.
