Post a successful planned migration or disaster recovery operation, it becomes important to make sure that the VMs recovered are able to connect to the IP network at the recovery site.
An administrator can always log on to each of the virtual machines and change the IP settings, but that could become a time-consuming ordeal when you have a lot of VMs to work with. VMware SRM allows you to create IP customization rules that enable SRM to reconfigure the recovered virtual machines with IP configuration required for it to be network-alive at the recovery site.
The customization rules are created for a network mapping (a mapping between port groups of protected and recovery sites). Since they are created for port group mappings, they are called subnet-level IP mapping rules.
Tip
To learn how to create network mappings, refer to the topic Creating resource, folder, and network mappings in Chapter 1, Installing and Configuring vCenter Site Recovery Manager (SRM) 6.1.
