+ During upgrade from 4.1 to 5.0, vRNI setup VMs are rebooted as part of the upgrade process.
+ It takes around 1-2 hours to upgrade a vRNI setup. But, if you are upgrading from 4.1 to 5.0 then a single node setup takes around 1-2 hours and around 3-4 hours to upgrade a cluster. The upgrade time does not depend on the number of nodes. After upgrade, vRNI takes around two to three hours to reflect the latest data in UI.
