we have a customer with 2 different versions of cisco waas
one is running 4.1 the other 4.0 both with their own CM
the CM of the 4.0 network should disappear and the sites should be migrated to the CM 4.1
the question is how to do this as for 4.0 you first have to do the devices before upgrading the CM and in 4.1 this is the other way around, first CM then the devices
is it possible that i first upgrade the devices, reboot and then assign them the new CM?
