How To Upgrade VMWare vCenter 6.7 U1 U2 U3 to 6.7 U3f – VirtuallyThatGuy

Posted on 3 September 20216 December 2022 by VirtuallyThatGuy

VMware recently came out with a CVE: CVE-2020-3952 that requires taking your existing VMWare vCenter to 6.7 U3f or 7.0.  Since going from 6.7 to 7.0 requires a re-deploy of the vCenter I thought doing an in place upgrade would be the quickest way to fix this security vulnerability.  Below you will find my step by step I followed to upgrade my vCenters.

Please Remember:
Go to the following URL to confirm version number you need for 6.7 U3f

https://docs.vmware.com/en/VMware-vSphere/6.7/rn/vsphere-vcenter-server-67u3f-release-notes.html

https://kb.vmware.com/s/article/2143838

Go to the following URL to confirm all other products are compatible with U3:

https://www.vmware.com/resources/compatibility/sim/interop_matrix.php#interop&2=3457

Once you confirm you won’t break anything with the above URLs I recommend any of the three ways below to backup your vCenter.  Personally, I know it is overkill but I perform all three because you can never be too cautious. 

  • Backup

  • Clone the vCenter VCSA

  • Snapshot

Step by Step Process

Step 1. Log into the VAMI

Log into the browser of your choice and type: https://FQDNorIPofvCenter:5480

Log in as root

Step 2. Pre-checks

At 70% the console will go blank and a refresh will bring you back to the screen and continue with it’s status update.

hit refresh and it should take you back to theupdate section

From the VAAMI you can see we are at the desired code level

https://i1.wp.com/digitalthoughtdisruption.com/wp-content/uploads/2020/04/1-7.png?resize=678%2C164&ssl=1

You can verify real quick in the about section that you are at the right version level by going to the vCenter at the top of the screen and looking at version information.

Summary:
As you can see in-place upgrades are relatively easy to do.  I hope everyone has non-disruptive upgrades and everything goes smoothly.  As always, I hope this article was helpful.
