Failover multiple EVS servers to pre-existing EVS servers on the target. If you choose this option,
instead of selecting the like-named equivalent, you will select the target EVS with which to setup

like-named target.
Configuring a standby cluster
The process for protecting a cluster with a like-named cluster is similar to protecting a standard
cluster. The following instructions point out the differences in configuration. For more information
about basic protection functions, see Protecting an Exchange Server on page 3-1.
1. In the Source Server field, select the source cluster that you want to protect.
2. In the Target Server field, select the same server.
NOTE: If you are running Exchange 2003 in mixed mode, the first installed EVS contains the MTA
(Message Transfer Agent) resource that is needed to communicate with versions prior to
Exchange 2003. If you do not failover all Exchange virtual servers, then any user who is
in a different mail store than the first one may not be able to route mail.
NOTE: The server name will be appended with the suffix “(like-named)”
