I have a small installation of ESXi 6.5 U2 on a PowerEdge T620 server. I installed this about a year ago and it's running 6.5 U2. I'd like to update to U3 (latest build), but I have a few questions I can't seem to find the answer to...
For a small installation like this, is it easier to manually apply updates, or better to use VCenter Update Manager?
Is it important to continue to use the Dell specific ISOs for the updates, or OK to download ESXi updates?
Do I manually update VCSA prior to updating to U3?
Any help would be great.
