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 VM Apps (Modern) or Networking using VLAN-backed, NSX Overlay/Segment and Modern NSX VPC.
