Currently we have a Windows SBC its running on a server that is also the file share / domain controller / print server. We decided to get a raspberry pi 3 Model B running raspian Jessie. just so we can put the sbc on its own computer. The question is what is the proper migration Method? do we need to wipe the phones and reprovision everything? Can we just change the ip address for the SBC and reboot the phones and let them reporvision? Any tests that we can run on the new sbc to make sure it is in fact making the tunell connection back to the Hosted 3cx server?
