- `switchover`
In certain circumstances, such as hardware or operating system maintenance,
it's necessary to take a primary server offline; in this case a controlled
switchover is necessary, whereby a suitable standby is promoted and the
existing primary removed from the replication cluster in a controlled manner.
The `repmgr` command line client provides this functionality.
it's desirable to promote a suitable standby to primary, and demote the current
primary to a standby role in a controlled way. This enables work to be carried
out on the former primary without interrupting the replication cluster.
The `repmgr` command line client provides this functionality with the
`repmgr standby switchover` command.
