Hi,   We currently have three Meraki networks configured as hub and spoke. We need to decommission the hub Meraki (MX1) and replace it with a third-party firewall (FW1).    MX1 Hub MX2 Spoke MX3 Spoke   FW1 New "Hub"   Preferably I would move one spoke at a time, but that does not seem to be possible since the IP space is the same on MX1 and FW1 and i get an error indicating this when trying to save the Non-Meraki Peer configuration for MX2.   Is the only way forward to turn off Site-to-Site VPN on MX1 and enable the Non-Meraki Peer on MX2 and MX3 at the same time, as well as changing both to Hub mode?   I should say my Meraki experience is non-existent.   Thank you. ...
