Abstract
In one aspect, a method to upgrade software on nodes in a clustered environment, includes terminating processes on a first node before upgrading the software on the first node, upgrading the software to a first version from a second version on the first node, running the processes on the first node after upgrading the software on the first node to the first version, determining whether a second node is about to upgrade to the first version of software, allowing transfer of site control from the second node to the first node, if the second node is about to upgrade to the first version of software and upgrading the software on the second node to the first version of software after the transferring of site control from the second node to the first node.
