I would like to know the upgrade sequence for CA nimsoft 6.2 to CA UIM 8.5. The nimsoft components are majorly on Windows Server 2008R2.
The core hub at the primary site is running in MS cluster environment for Standby. There is Primary and Secondary UMP's with Microsoft NLB setup.
The Remote Sites are connected via the Tunnel server which also has its HA and all Remote hubs are sending monitored data from devices to the core hub via the tunnel servers.
How can we upgrade all of the UIM components (primary hub, client hubs, Robots, UMP's) with minimum downtime. Also, does upgrading one component at a time will lead to data loss?
Thanks & Regards,
