My VPN gateway is stuck in the Migrating state and I cannot remove it.

Hi @JJ Streicher-Bremer,

Welcome to Microsoft Q&A Platform.

If the VPN Gateway remains stuck in the Migrating state for an extended period, you can abort the migration using the Azure CLI command provided below.

az network vnet-gateway migration abort --gateway-name "gateway-Name" --resource-group "rg-name" --no-wait

Once the abort operation completes successfully.

Please use below command to delete the Gateway.

az network vpn-gateway connection delete -g MyRG -n MyConnection --gateway-name MyGateway

For Migration review the following migration considerations before attempting the migration again. First, validate that your resource is eligible for migration:

• Before initiating VPN Gateway migration, ensure that the GatewaySubnet has at least three available IP addresses within the current address prefix.
• If your GatewaySubnet is /28 or smaller, the migration tool may fail. In this case, add multiple prefixes for subnet to expand the subnet to /27 or larger before retrying the migration.
• If ExpressRoute and VPN Gateway coexist, it is recommended to first migrate Basic IP resources to Standard IP on the VPN Gateway before proceeding with migration.
