With the Gateway migration experience, customers can use the Azure Portal or PowerShell scripts to deploy a second Virtual Network Gateway within the same GatewaySubnet of the Virtual Network. During the migration phase, once initiated by the customer, Azure will transfer both the control plane and data path configurations from the existing gateway to the newly deployed one. This process will result in two operational Gateways within the same Gateway Subnet. After the migration is successfully completed, customers can remove the original Gateway, leaving the new Gateway in place for continued Private Connectivity.
