Special Upgrade Considerations
When an installed CMS HA system is subject to a software upgrade (or when one of the servers is restored to service after a system failure event), the alternate server continues to collect data without interruption. Since manual synchronization between the primary and secondary servers is a key maintenance objective for HA systems, CMS upgrades should proceed in a manner that restores servers synchronization with the least time and effort, while minimizing data loss as much as possible.
If the customer CMS server has any custom features, such as Custom Reporting, custom interfaces, LAN printers, token ring, etc., PSO must be contacted before the upgrade process is initiated.
For further details of the CMS upgrade process, see Chapter 3 (Upgrading HA systems).
