Hi , I would personnaly use Python to developp a small script to achieve your needs. The Meraki Python SDK is pretty well made and easy to learn ! I usually test individual endpoints with Postman , but when doing automation I use Python. I'm not sure if you can do that in Postman. Here is some pseudo code. Loop through all Networks Filter networks on something that you desire ( name , tag [...] ) Get the Vlan info ( supply the networkID and the Vlan ID ) Update the same Vlan ID but without the groupPolicyID , remove it listOfNetworks = getOrganizationNetworks
for Network in ListOfNetworks:
if "Criteria" == Network["name"]: ###Or Anything to match desired networks
Vlan = getNetworkApplianceVlan(Network['id'],VlanID)#networkID from "Network" and vlanID
if "NameOfYourVlanToEdit" == Vlan["name"]: ### Just to make sure its the good vlan
updateNetworkApplianceVlan ###Update same Data without groupPolicyID Obviously test it before looping throught all your networks and I'm not responsible for any mess created 🙂
