vCenter 6.7 upgrade walkthrough

VMware recently announced a new vSphere release, version 6.7. It includes new features like the Per-VM EVC and support for embedded PSC and vCenter in enhanced link mode (ELM). In this post, I will show a slideshow of the upgrade process in a topology with the Platform Service Controller separate from the vCenter server. Basically, this only means that you have to perform the upgrade twice. Before starting your upgrade make sure you have a good backup of your system, consult the vSphere 6.7 Release Notes and the related essential information about compatibility.  First, we upgrade the external PSC, you’ll need a temporary IP address to deploy the new image before doing the final cut. The upgrade order is published in this VMware KB-53710. Make sure that all the host and IP address information is resolvable using DNS and that the NTP servers are working.

Once you have the PSC upgraded and running, you can move on to the vCenter in a similar process.

The topologies must stay the same when using the upgrade script. If you want to change from two VMs into an embedded deployment with the PSC and the vCenter in a single VM, then you’ll have to re-deploy your vCenter appliance.
