VCF 9.1 - VCF Download Tool (VCFDT) Cheatsheet

05.27.2026 by William Lam // 8 Comments

The latest release of VMware Cloud Foundation (VCF) Download Tool (VCFDT), which ships as part of VCF 9.1, includes a number of enhancements for downloading VVF and VCF installation and upgrade binaries.

For new users of VMware Cloud Foundation Download Tool (VCFDT), I thought it would be useful to put together a quick cheat sheet covering some of the most common workflows, ranging from configuring an activation code and downloading the required VCF 9.1 binaries for initial deployments and upgrades, to the new workflow for downloading ESX patches and updates.

I have even found myself repeatedly using the --help command just to locate a specific option or workflow, so hopefully this serves as a useful reference for both new and existing users, including myself! 😅

VCF 9.1 - Demystifying Supported Upgrade Paths to 9.1

05.23.2026 by William Lam // 16 Comments

The rapid advancement of frontier AI capabilities, including recent developments from Anthropic Mythos, keeping software and infrastructure up to date has become a critical priority for many IT organizations.

VMware vSphere Foundation (VVF) and VMware Cloud Foundation 9.1 introduce a ton of powerful new private cloud capabilities, which has generated tremendous interest from both customers and partners, ranging from new deployments to modernizing existing environments, all with the goal of building a more secure and resilient private cloud platform while also helping address the rapidly evolving threat landscape.

One area that has significantly changed from earlier VCF releases prior to VCF 9.0 is around upgrades, which has been a major source of confusion, even for myself at times. I will not try to defend some of the confusion and misconceptions from the past, but I will say that VCF 9.1 introduces more flexible upgrade paths, allowing customers to take advantage of the latest capabilities while also meeting them where they are currently at in their Private Cloud journey.

With that said, I am hoping this quick blog post, along with some visuals, will help demystify the supported upgrade paths to VCF 9.1, including some of the common misconceptions around specific feature capabilities and future direction, especially as it relates to VCF Automation VM Apps (Traditional) and All Apps (Modern) or Networking using VLAN-backed, NSX Overlay/Segment and Modern NSX VPC.

VCF 9.1 - Quick Tip: Using the VCF Installer as a Standalone Pre-Check Tool

05.22.2026 by William Lam // Leave a Comment

The VCF Installer appliance is used to deploy either a VMware vSphere Foundation (VVF) or a VMware Cloud Foundation (VCF) deployment. Customers can re-use their existing components (vCenter Server, NSX Manager, VCF Operations or VCF Automation) that have already been deployed or they can start from scratch, deploying all brand new components.

To accommodate the wide range of deployment permutations, the VCF Installer includes a comprehensive set of validations and pre-checks that are performed prior to deploying a new VCF Fleet.

I recently recieved an interesting question on whether the VCF Installer could be deployed just for the purpose of environment validation without deploying anything?
