Transfer DNS from old Win Server to Azure DNS
you can find all files that you need in %systemroot%\system32\dns.
Azure DNS supports importing and exporting zone files by using the Azure command-line interface (CLI).
The Azure CLI is a cross-platform command-line tool used for managing Azure services.
It is available for the Windows, Mac, and Linux platforms from the Azure downloads page.
Import a zone file
To import a zone file for the zone contoso.com.
- Sign in to your Azure subscription by using the Azure CLI.
- azure login
- Select the subscription where you want to create your new DNS zone.
- azure account set <subscription name>
- Azure DNS is an Azure Resource Manager-only service, so the Azure CLI must be switched to Resource Manager mode.
- azure config mode arm
- Before you use the Azure DNS service, you must register your subscription to use the Microsoft.Network resource provider. (This is a one-time operation for each subscription.)
- azure provider register Microsoft.Network
- If you don’t have one already, you also need to create a Resource Manager resource group.
- azure group create myresourcegroup westeurope
- To import the zone contoso.com from the file contoso.com.txt into a new DNS zone in the resource group myresourcegroup, run the command
azure network dns zone import.
- This command will load the zone file and parse it. The command will execute a series of commands on the Azure DNS service to create the zone and all of the record sets in the zone. The command will also report progress in the console window, along with any errors or warnings. Because record sets are created in series, it may take a few minutes to import a large zone file.
- azure network dns zone import myresourcegroup contoso.com contoso.com.txt
