How to Update a VMware vCenter Server Appliance

Read this guide to learn how to update a VMware vCenter Server Appliance (VCSA) to a new version or install a patch.

Step 1: Back up the vCenter Server Appliance

Before upgrading your VCSA, it is strongly recommended to back it up. If you do not already back up your vCenter appliance, follow my guide, How to Backup a vCenter Server Appliance to a Windows Share.

After setting up the Windows share for backing up the appliance, use the BACKUP NOW option to take a manual backup. I’m not taken a backup because I have a scheduled backup that runs daily.

Step 2: Update the vCenter Server Appliance

1. Sign in to the VCSA’s management interface via a browser on port 5480. The VCSA’s management portal is the same URL you use to log in to vCenter but includes “:5480” at the end.

Here is the management URL for the VCSA in my home lab

2. Once you log in, click the Update menu on the left pane. Then, wait for the appliance to download available updates – it may take a little while.

According to the message on the Update page “Updates and patches are cumulative. The most recent update or patch in the table below will contain all previous patches.” So, you just need to install the latest update.

3. To display the latest update on top of the list, click the Release Date column and select the update. From the screenshot below, the latest update was released on July 18th, 2024.

As of this date, the update version was 8.0.3.00100. So, I will install this VCSA release.

4. Once you select the update by clicking the radio button on the left, click STAGE AND INSTALL.
5. Scroll to the end of the license agreement accept it and click NEXT to continue. Then, wait for the Pre-update checks to run.

6. Review the pre-update check results. If you receive a warning – “Files that cannot be used with Lifecycle Manager will not be copied from the source. These files include VM guest OS patch baselines, host upgrade baselines and files, and ESXi 6.5 and lower version host patches baselines.” – click IGNORE AND CONTINUE.

7. On the “Join the VMware Customer Experience Improvement Program” page, uncheck the checkbox if you do not want to participate in VMware’s CEIP.

8. Then, on the “Backup vCenter Server” page, read the information and if you have not taken a backup, DO IT before you continue.

However, if you have already taken a backup, check the “I have backed up vCenter Server and its associated databases.” checkbox, and click FINISH.

Wait for the update to complete.

In the rare instance that an upgrade or patch breaks your VCSA,

Conclusion

Upgrading a vCenter Server appliance is a normal task that VMware admins will perform from time to time. The upgrade is quite straightforward, but before upgrading the appliance, it is strongly recommended to back it up.
