@VCVC Thank you for your question. If I am not mistaking what you are trying to achieve is migrating your DNS operations from AWS Route 53 to Azure DNS Zone. You should be able to export your DNS zone from Route 53 and import it to Azure DNS zone. Below are the steps you can follow:
- Export all your domain’s DNS records into a BIND file format, readable by other DNS services. You can use the following tool: https://github.com/barnybug/cli53
- Then, create a new DNS Zone and import the DNS record on Azure using Azure CLI following this documentation: https://learn.microsoft.com/en-us/azure/dns/dns-import-export
- Retrieve the name servers and verify that the resolution is effective using one of the Azure Name Servers. https://learn.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns#retrieve-name-servers
- Once you validate the resolution, you can update the DNS delegation in your domain registrar (Route 53, GoDaddy, etc.) since you will have the list of the NS servers from your new Azure DNS zone created. https://learn.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns#delegate-the-domain
