VMware vCenter is the next component to upgrade in our VMware Horizon View upgrade. vCenter doesn't need to be upgraded with every Horizon View upgrade but needed when upgrading between major versions.
It is strongly recommended to consult the interoperability matrix prior to a vCenter upgrade.
Note that components other than vCenter need to be considered. VMware vCenter needs to be upgraded with its co-depended products. Common co-dependent products include vShield, SRM, NSX networking, Operations Manager, vRealize, and so on.
Depending on the complexity of the environment, plan for a 1 to 4-hour outage of the vCenter for the upgrade.
