What does life look like after VMWare/VSphere?

To put this into context, we currently use VSphere to manage our production servers over three different HP ProLiant DL380 Gen10 boxes. We are currently a live environment under a VMWare license, but have been slowly moving off of the vSphere environment with a goal of being fully cloud/Azure for our business, so we are down to just a handful of non-critical servers left in our environment. We likely will not be renewing our VMWare contract after this year, as the servers still in use are our AD servers (moving to Azure/Entra fully later this year), old application servers used rarely, and a couple of Linux boxes, or old servers we are keeping around just in case but have shut down. That being said, my concerns are what will happen to the existing hardware/servers and how they are managed if we let the contract lapse for VMWare, and what that environment looks like going into the future. Can we still continue to using the VSphere software environment and existing hardware over the next several years knowing we just would not have support if something were to go offline or need updates? Or does something stop working once our license expires? I'd like to still use the VSphere interface to keep copies of our offline servers, take snapshots, and still create/mange servers for non-critical systems, such as if I wanted to build a test server, or a Linux server with that hardware cluster, or for IT file storage. So basically, once that VMWare support expires and we're sitting on the hardware afterwards - what can we still do and what should be plan for with that equipment?
