Step by step procedure to update vCenter sever 6.7 appliance

Steps to patch VMware vCenter 6.7 appliance



  • Please take a non-memory, non-quiesced snapshot of the vCenter VM (if standalone), before implementing any change.
  • In case there are multiple vCenter servers linked, do take powered down snapshots of all nodes before proceeding with vCenter update.
  • If PSC is external do take powered down snapshot/s of all PSC's as well.
  • If there are multiple vCenter's linked with external PSC we need to update all PSC nodes first and then proceed with vCenter nodes.
  • If DRS is set to Fully Automated, please change it to Manual while updating.
  • Make note of the host IP/FQDN where vCenter/PSC VM is deployed.
  • Ensure that you have the login credential for the ESXi host which has the vCenter VM.

Congratulations on the article.

Have a question, on average how long it took to perform the installation, whether to contact or counting on the restart?


Thanks, @Arthur_Oliveir1 

Based on testing in the lab, the upgrade from 6.7 U3a ( to 6.7 U3n ( took around 40 Minutes overall.

Staging the Patches - 13 Minutes
Installing the Patch, including reboot and service startup - 27 Minutes

Please note, many factors could influence the time taken for upgrade (patch download speed, ESXi performance, etc..)

I hope this helps to address your query.

Hello @baijupthank you for your return.

The doubt was clarified.

Best Regards.

Please clarify if we have Vcenter appliance 6.7u3l with external PSC, do we need to apply the same patch VMSA-2021-0010 to PSC first and than to Vcenter?

Also what is the sequence if we have 2 Vcenter appliances and 2 external PSC's in linked mode. Thank you

@Ela_ivari we have to apply same patch on PSC as well. First apply patch on PSC and then VC.


If there are 2 vCenters with external PSC in linked then update sequence will be to update both PSC first and then VC:

- Update PSC1
- Update PSC2
- Update VC1
- Update VC2
