About changing network interfaces
You must change the network interfaces and network identities in the DSR configuration.
For the changes to work properly you must back up the target system in compliance with the procedures that are part of discovering a configuration.
See Discovering a configuration.
If you installed the client on the target system and backed it up in compliance with the procedures above, you can do the following:
Import the NIC information from that configuration.
Map the network identifiers (IP address, netmask, and domain name) from the protected client to the NICs in the target system.
If you did not save the target system's configuration, you must determine the MAC addresses of the NICs in the target system. Then add the network interface information manually to the DSR configuration.
More information is available on procedures to import and map interfaces or change them manually.
