You can customize the IP properties for multiple virtual machines on the protected and recovery sites by using the DR IP Customizer tool and by defining subnet-level IP mapping rules.

In previous releases of Site Recovery Manager, you customized IP properties for multiple virtual machines by using the DR IP Customizer tool. In addition to DR IP Customizer, with Site Recovery Manager 5.8 you can customize IP properties for multiple virtual machines by defining subnet-level IP customization rules.

You can use subnet-level IP customization rules in combination with DR IP Customizer.

  • Using DR IP Customizer is a fast way to define explicit IP customization settings for multiple virtual machines by using a CSV file.

  • You apply subnet-level IP customization rules to virtual machines by using the vSphere Web Client.

Virtual machines that you configure by using DR IP Customizer are not subject to subnet-level IP customization rules. You can achieve the same IP customization results by using either DR IP Customizer or IP subnet rules. In Site Recovery Manager 5.8, the DR IP Customizer provides more control over IP configuration of individual virtual machines, such as customizing static IPv6. This control is useful when you upgrade from an earlier version of Site Recovery Manager in which you used DR IP Customizer.
