from Wikipedia, the free encyclopedia

In information technology, a switchover is a change from a primary system to a standby system.

Unlike a failover , which describes an unplanned change to the standby system and which occurs, for example, due to the failure of the primary system or the network to the primary system, a switchover is understood to be a planned change that is specifically initiated by a system administrator . A switchover is carried out, for example, to check the functionality of the standby system or to make the services temporarily available on the standby system during maintenance work on the primary system.

A switchover can be made possible by cluster manager software or, in the case of standby databases, by extensions from the database manufacturer or third-party providers.
