Error: The Compatibility of plug-in package "com.vmware.vrUi-#### cannot be validated during vCenter Server upgrade precheck

Products

• VMware vCenter Server
• VMware Live Recovery

Issue/Introduction

Symptoms:

• The vCenter upgrade pre-check displays the following error: "The compatibility of plug-in package(s) "com.vmware.vrUi-####" with the new vCenter Server version cannot be validated. They may not function properly after vCenter Server upgrade."

• A compatible version of VMware Live Site Recovery (SRM) or vSphere Replication (VR) is already installed (e.g., 9.0.x), yet the installer flags an older version (e.g., 8.8.x).

• The stale plugin may not be visible in the vSphere Client "Client Plugins" view but remains on the filesystem.

Environment

• VMware vCenter Server 7.x, 8.x

• VMware vSphere Replication (VR) 9.0.x

• VMware Live Site Recovery (SRM/VLSR) 9.0.x

Cause

Stale extension registrations or cached plugin package folders remain on the vCenter Server Appliance (VCSA) filesystem after an uninstallation or upgrade of Site Recovery Manager or vSphere Replication.

Resolution

If you have already confirmed that a newer, compatible version of the plugin is active, or if the associated product has been decommissioned, follow these steps to remove the stale warning:

1. Take a snapshot of the vCenter Server Appliance. (Offline snapshot if it is in linked mode)

2. Open SSH to the vCenter as root.

3. Navigate to the client plugin package directory: cd /etc/vmware/vsphere-ui/cm-service-packages/com.vmware.cis.vsphereclient.plugin/

4. Identify the stale plugin folder (e.g., com.vmware.vrUi-8.8.0.23263429).

5. Remove the stale directory: rm -rf <stale_plugin_folder_name>

6. Restart the vSphere UI service: service-control --restart vsphere-ui

Additional Information
