Downgrade VMware Virtual Machine Hardware Version
You’ve upgraded to the latest version of vCenter Server, ESXi, VMware Tools, and either scheduled the VM Hardware upgrade on the next reboot or you’ve manually upgraded the hardware version for each machine.
Everything has gone according to plan with no issues during the scheduled maintenance. However, after everything has been done, you find that one of your 3rd party solutions no longer works and you find yourself staring at a list of errors. In this example, let’s say it’s your disaster recovery DR solution that’s not compatible.
Don’t worry, I’ll show you a quick way to revert and also point out the way VMware recommends you do it. As you try to figure out why it’s not working, you quickly go through the logs, and you determine that the VM hardware version that you’re running on-prem is not compatible with your DR solution since they are not running the latest version of vSphere within their datacenter.

I was also curious about the VMDK’s ddb. From what I can tell, there’s was no change needed, unless of course, you are migrating the VM to an older environment, that is, some other datacenter that is running an older version of vSphere. In that case, I would recommend that you create a VM in your inventory with whatever native hardware version being run and take note of the VMDK’s version number and match it.
You’ll need to modify the path for your specific datastores. One last thing, I did try to find a PowerShell command to downgrade the version. While there is a built-in command to change the version for a VM, it only works to upgrade to a specific version, not downgrade.

You’ll need to install this tool, but there are limitations since you can only change the VM version to 7, 8, 9, 10, or The other thing is that you need to set up a job for each VM that you need to revert back. Create a new virtual machine with the required hardware version and attach the existing disk from the virtual machine. This option can be very time consuming if you have a lot of VMs that need to be reverted back to an older version and prone to mistakes since you have to match up the correct settings for each VM such as vCPU count, memory, number of disks, reservations, etc.
