Since its introduction in vSphere 6.7.GA, Update Manager (VUM) User Interface for vSphere Client (HTML-based) was gradually improved through subsequent patch/update releases. Although with vSphere7.0, the 6.7 release line went out of active development, we still support it and even add some features to it.
6.7.0 was the release in which we shipped the VUM plugin for vSphere Client (HTML-based) with only the basic functionality implemented.
6.7 Update 1 addressed this gap. We ported most of the leftover functionality from the VUM plugin for the vSphere Web Client (Flash-based) and claimed parity with it. Not only that, but we improved some of the workflows and added a lot of new features, like updating firmware in VSAN-enabled clusters.
6.7 Update 3l re-introduced parallel remediation for hosts in maintenance mode – a revised and improved version of a feature that can save a lot of remediation time.
6.7 Update 3m, currently the latest one, introduced VUM plugin for vSphere Client (HTML-based) running on vCenter Server for Windows. So far customers running vCenter Server for Windows could use VUM only on the vSphere Web Client (Flash-based), but since the recent announcement for the end of official support for Adobe Flash player, vSphere Client (HTML-based) become the recommended UI for managing vSphere environment. This update allowed our customers that run VUM on vCenter Server for Windows to switch to the vSphere Client (HTML-based).
This is not a comprehensive list, but one containing the major cornerstones. You can find more detailed information in vSphere Update Manager Release Notes for Update and Patch Releases.
Although the vSphere 6.7 General Support Period was extended, it approaches relatively soon. If you’re wondering “what’s next” – vSphere 7.0 introduces a completely new way to upgrade clusters, so check it out!
