I've modified a bit this script, for it to able to support multiple input zones from Route53 at once (Azure login and password are only asked once). Look for ZoneIds, ZoneNames and DomainNames arrays in main() (I didn't have time to make the code straightforward, sorry).
Recently, I was tasked with migrating our Amazon Route 53 DNS records to Microsoft Azure DNS. It's not uncommon to have several hundred DNS records for a given zone, and entering them by hand would be nothing less than tedious. So rather than trudge through just under five hundred records and hope that mistakes weren't introduced, I figured a script would be better suited for the task.
This script assumes the following:
-
You've installed and configured the AWS Command Line Tool. For more information on how this is accomplished, please read: http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-set-up.html
-
The Azure Windows PowerShell cmdlets are installed. For more on this, check out: https://azure.microsoft.com/en-us/documentation/articles/powershell-install-configure/
-
You've created a target DNS Zone in Microsoft Azure. A reference on how to manage Azure DNS zones can be found at: https://azure.microsoft.com/en-us/documentation/articles/dns-operations-dnszones/
Set your Microsoft Azure and Amazon Web Services credentials in the User Defined Variables section of this script. If you're unsure on what your AWS Hosted Zone Id is, try issuing this command in the AWS CLI: "aws route53 list-hosted-zones". This will produce a list of all the DNS zones accessible with your AWS IAM account.
Execute the script. Shortly after execution, it will request Azure login credentials. Be sure to use an account with appropriate permissions for the target subscription ID and resource group.
Once logged in, the script will begin the migration. The basic steps involved are:
- Log into Azure and select the target subscription and resource group.
- Export the Route 53 DNS records as json.
- Parse the export and prepare the records for import into Azure DNS.
- Import the records into Azure based on a number of variables, such as record type, while avoiding import of SOA and NS records. These are automatically created with the Azure DNS zone
As always, test your work whenever possible in a staged environment. Inspect the results, and only once you're satisfied, run it against a production DNS zone. This script is intended to be run once for migration purposes.
