 In some circumstances, like during [upgrades](replication/updating_the_geo_nodes.md) or a [planned failover](disaster_recovery/planned_failover.md), it is desirable to pause replication between the primary and secondary.
 
 Pausing and resuming replication is done via a command line tool from the secondary node.
