Hi Bala, If you need to upgrade them all first but don't know exactly where they will all be deployed initially, create one network, add them all in and then when you go to the firmware upgrade page mentioned by @BlakeRichardson you can just select this one network and they will all upgrade. To add them to a network, first create a network from the top left option as below: Then give it a name, make sure you choose combined and tick the box at the top of the inventory list to add all devices I If you do know what goes where, then simply create one network for each location (or however else you might want to divide them up) and then you can upgrade each network. Don't worry too much about getting it perfect first time, you can rename networks and move devices between them easily and unless you have an MX set up as a VPN concentrator for SDWAN, your users wouldn't even know. Cheers, Charles
