If upgrading from a LiteSpeed version prior to 6.x, please uninstall that version on all nodes of the cluster.
Open the Polyserve Management Console to confirm the Host (Active Node) for the SQL instances on which you wish to install LiteSpeed
Download the LiteSpeed installation program to the Active Node, and begin the installation process.
When you reach the SQL Instances screen, verify that the displayed Instance Names correctly match the names of the virtual SQL instances running on the Active Node of the cluster on which you are installing LiteSpeed If not, edit the field(s) appropriately.
Open the Polyserve Management Console and fail over (re-host) the virtual SQL instances to the passive node of the cluster.
Repeat Steps 3 through 5 for the remaining nodes in the cluster.
