Upgrading the vSphere Client VCM Plug-in
The vSphere Client VCM Plug-in integrates VMware vCenter Configuration Manager into the vSphere
Client to provide VCM data and functionality within vCenter. After upgrading VCM, you must upgrade
the Plug-in, which means vCenter users must un-register it and then re-register it.
Upgrading the Plug-In
To upgrade the vSphere Client VCM Plug-in, follow these steps:
1. Upgrade VCM.
2. Manually un-register the pre-VCM 5.3 version of the Plug-in, as described in Un-register the Previous
Version of the Plug-in in Un-register the Previous Version of the Plug-in.
3. Register the new Plug-in by following the instructions in "Registering the vSphere Client VCM Plug-in"
on page 143.
Un-register the Previous Version of the Plug-in
If you have already upgraded VMware vCenter Configuration Manager, you must manually un-register
the previous version of the Plug-in before registering the VCM 5.3 Plug-in. Although the upgrade to VCM
removes files for the previous Plug-in, and installs the new Plug-in files in new locations and with new
names, it does not register the new Plug-in with the vSphere Client. To un-register the existing Plug-in,
follow these steps.
1. Browse to the following link, where "{vCenter machine name}" is the name of your vCenter 4
Server instance:
https://{vCenter machine name}/mob/?moid=ExtensionManager
2. In the Methods area, click the UnregisterExtension link.
3. Enter the following string value for extensionKey: com.CM.VirtualCenterCompliancePlugIn
4. Click Invoke Method.
