Switchover

From Wikipedia, the free encyclopedia

Switchover is the capability to manually switch over from one system to a redundant or standby computer server, system, or network upon the failure or abnormal termination of the previously active server, system, or network. Switchover happens with human intervention, unlike Failover.

A switchover would usually be initiated in order to perform system maintenance, such as installing patches, upgrading to a new release, or upgrading your system. In other cases, the overall system is complex enough that automatic failover is not possible.
