After a plug-in has been unregistered, the vsphere-ui service detects the change immediately. The cached copy of the plug-in manifest is deleted from the cache.

When a plug-in is upgraded, the vsphere-ui service detects the change as soon as the plug-in registration entry is updated with a new version number. At that time, the old plug-in version is undeployed, the cached copy of the manifest is removed, and the new plug-in version is deployed.

If plug-in resources are upgraded without changing the version number, such as when developing a plug-in, the vsphere-ui service does not detect the change. To deploy plug-in changes during development, use

pluginDeveloperMode

to enable the

Redeploy

button in the user interface. For more information, see Redeploying Plug-ins During Development.
