There are two options if Classic devices need to be used in an Evolution network:
1. Update unpaired Classic units individually to Evolution firmware and then create a new Evolution network.
2. First pair all the Classic units to a Classic network, then select 'Upgrade to Evolution firmware' from 'Network setup'. After first checking that all the Classic devices can be upgraded, this option will start the network upgrade process. For more instructions, please see:
NOTE: Only devices which display as Classic in the 'Nearby devices' list can be updated to Evolution and used within an Evolution network.
