Solved: How to Upgrade VMware Tools without Reboot in vSphere?

Problem Symptom

Rebooting production servers is always a difficult and complicated process. If you use the Automatic Upgrade option for upgrading VMware Tools from vSphere, the production server will automatically reboot after the upgrade is finished. This article will show you how to prevent server from reboot automatically after VMware Tools have been upgraded.


Step 1: Select the Automatic Upgrade option.

Step 2: Enter the following text in the Advanced Options: /s /v "/qn REBOOT=ReallySuppress"

Select the Automatic Upgrade option and enter ReallySuppress parameter in Advanced Options.

Step 3: Click on the UPGRADE button to proceed to upgrade VMware Tools automatically using ReallySuppress advanced option.

Step 4: After VMware Tools upgrade completed, VMware tools will stop and restart without restarting server. You can check the VMware Tools version from Task Manager.

Once VMware Tools upgrade completed, it will restart automatically and show the latest version number in Task Manager.

Step 5: Due to the full upgrade process requires a reboot, you can schedule a reboot in later time to properly complete the procedure.
