 This step is your opportunity to test and validate your new App Service Environment v3. By default, traffic is sent to your App Service Environment v2 front ends. If you're using an ILB App Service Environment v3, you can test your App Service Environment v3 front ends by updating your private DNS zone with the new inbound IP address. If you're using an ELB App Service Environment v3, the process for testing is dependent on your specific network configuration. One simple method to test for ELB environments is to update your hosts file to use your new App Service Environment v3 inbound IP address. If you have custom domains assigned to your individual apps, you can alternatively update their DNS to point to the new inbound IP. Testing this change allows you to fully validate your App Service Environment v3 before initiating the final step of the migration where your old App Service Environment is deleted. If you're able to access your apps without issues that means you're ready to complete the migration.

This command also deletes your old environment. You have 14 days to complete this step. If you don't complete this step in 14 days, your migration will automatically be reverted back to an App Service Environment v2. If you need more than 14 days to complete this step, contact support.
 
 If you find any issues or decide at this point that you no longer want to proceed with the migration, contact support to revert the migration. Don't run the DNS change command if you need to revert the migration.
