This section describes rolling upgrades.
Users with high availability (HA) clusters under heavy transaction loads who need to upgrade to a newer version of MarkLogic Server must do so seamlessly. A rolling upgrade, during which hosts in a cluster are upgraded one by one, addresses this need.
Rolling upgrades can upgrade a large cluster with many hosts to a newer version of MarkLogic Server without incurring any availability downtime or transaction interruption. A rolling upgrade can also be used to apply patches to multiple hosts. Rolling upgrades can be performed on both a primary cluster and a disaster recovery (DR) cluster.
Note:
You can upgrade your cluster with a minimal amount of transactional downtime (less than 5-10 minutes) without using the rolling upgrade feature. Consider whether the tradeoff in added complexity warrants using rolling upgrades instead of the regular upgrade process. See Upgrading from Previous Releases in Install MarkLogic Server for information about the regular upgrade process.
