How do you migrate from legacy DNS solutions to DNS policies and split views?

2 Plan your DNS policies and split views

Next, you need to plan your DNS policies and split views based on your migration goals and challenges. You can use the DNS Policy Wizard or PowerShell cmdlets to create and configure DNS policies and split views. A DNS policy consists of a set of rules that define how the DNS server responds to queries that match certain conditions. A split view is a special type of DNS policy that allows you to serve different sets of records to different clients, based on their source IP address. For example, you can create a split view to serve internal records to your corporate network and external records to the internet.

3 Test your DNS policies and split views

Before you apply your DNS policies and split views to your production environment, you need to test them in a lab or staging environment. You can use tools such as NSLOOKUP, DNSCMD, or PowerShell to verify that your DNS policies and split views work as expected and do not cause any errors or conflicts. You can also use performance counters, event logs, or network monitoring tools to measure the impact of your DNS policies and split views on your DNS server and network traffic.

4 Backup your existing DNS configuration

Before you migrate, you need to backup your existing DNS configuration and zones, in case you need to revert or troubleshoot any issues. You can use tools such as DNSCMD, PowerShell, or the DNS Manager console to export your DNS settings and zones to a file or a remote location. You can also use Windows Server Backup or a third-party backup solution to backup your entire DNS server.

5 Apply your DNS policies and split views

Once you are ready to migrate, you need to apply your DNS policies and split views to your production environment. You can use tools such as DNSCMD, PowerShell, or the DNS Manager console to enable or disable your DNS policies and split views. You can also use the DNS Policy Wizard or PowerShell cmdlets to modify or delete your DNS policies and split views. You need to ensure that your DNS server is properly updated and synchronized with your other DNS servers and clients.

6 Monitor and troubleshoot your DNS policies and split views

After you migrate, you need to monitor and troubleshoot your DNS policies and split views to ensure that they are working correctly and efficiently. You can use tools such as NSLOOKUP, DNSCMD, or PowerShell to query your DNS server and check the results. You can also use performance counters, event logs, or network monitoring tools to analyze the performance and health of your DNS server and network traffic. You can also use the DNS Manager console or PowerShell cmdlets to view and manage your DNS policies and split views.
