Patching or Upgrading vCSA and PSC

VMware regularly releases patches for the vCenter Server Appliance that might be related to third-party products in the platform, core product functionality, or both. You can use the Appliance Management Interface or the appliance shell to apply patches to a vCenter Server Appliance that contains a vCenter Server with an embedded Platform Services Controller, a vCenter Server with an external Platform Services Controller, or a Platform Controller.

VMware makes patches available monthly. These patches can only be applied in between major releases of vCenter Server Appliance. For example, patches released for the initial release of vCenter Server Appliance 6.7, are not applicable to vCenter Server Appliance 6.7 Update 1, as any patches previously made available will be included with the Update 1 release.

VMware distributes the available patches in two forms, one for ISO-based and one for URL-based models of patching.

You can download the patch ISO images from VMware Repository. VMware publishes a single type of ISO image that contains patches.
You can configure the vCenter Server Appliance and Platform Services Controller appliance to use a repository URL as a source of available patches. The appliance is preset with a default VMware repository URL.

In this blog I am briefing about the vCSA upgrade/patch using GUI, Offline and Command line.
