How to Update to vCenter Server 6.7 Update 3b

I will demonstrate an online update from vCenter Appliance Management console. I logged in to the appliance management console (https://<vCSA-FQDN>:5480/) using the root appliance password, then I navigated to Update menu. I can see my current version is 6.7.0.41000 and I have an available update to 6.7.0.42000 (which is vCenter Server 6.7 Update 3b). I will click on “Stage and install” link.

Next step is to accept the end user license agreement (EULA). Check the “I accept…” checkbox and click on “Next”.

The installer will run pre-update checks now. If everything is in order, the wizard will jump to the next screen. You can see a downtime estimation (which proved to be extremely overestimated; in my case the upgrade took around 5 minutes instead of the estimated 369). Confirm you have a backup of vCenter Server and click on “Finish”.

The wizard will pass through a series of updates while the vCenter Server is upgraded.
