Upgrading my vSAN Cluster

Some time ago I decided to upgrade my home lab environment running vSphere (from 6.0 U3 to 6.5 U1) and vSAN (from 6.2 to 6.6.1).

I started with upgrading the vCenter appliance which is quite a smooth upgrade process. The only problem I had is that initially the upgrade wizard did not give me a choice to select “Tiny” as the size for the new appliance. This appeared to be an issue with the disk usage of the existing appliance. After deleting a bunch of old log files and dump files from the old vCenter appliance I retried the upgrade wizard and this time the “Tiny” option was available – which is a better fit for my “tiny” lab 🙂 – and the upgrade process went just fine.

Next up was the ESXi upgrade (I have three hosts). First try was doing an in-place upgrade using Update Manager.
