I Broke My VCF 9.1 Upgrade So You Don't Have To!

Most upgrade guides show you a clean upgrade, here at LAB2PROD I aim to break things then fix them!

In this video I will upgrade VCF 9.0.2 to 9.1 whilst breaking things along the way. We will resolve them together, so you are better armed with knowledge to troubleshoot in your own environment.

That includes everything; pre-check failures, CIDR conflicts, FQDN mismatches, NSX edge failures, DNS failures, and every troubleshooting step left in. Nothing cut.

If you're planning a VCF 9.1 upgrade, this is the video I wished existed before I started.
