This post is going to quickly explain you with the different procedures to downgrade your Virtual Machine Hardware Version from vmx VM Hardware Version 10 to vmx-9 VM hardware version 9. You may ask me the question why do you want me to downgrade the Virtual Machine Hardware Version.
Downgrading Virtual Machine Hardware version may required if you have come across one of the below situation:. You will not be able to manage the VM with higher Hw version in previous versions of Host. Virtual Machine with Legacy operating system does not support the latest hardware devices supported by HW version So you may downgrade the Virtual Machine hardware version to compatible with your legacy guest OS.
Another 3rd reason which you may not face frequently but i faced the issue. In that situation, you may need to downgrade the Virtual Machine hardware version from 10 to 9 to get that managed by vSphere windows client However,You will be able to manage to perform almost most of tasks using PowerCLI scripting if you are familiar with powerCLi scripting..
You may receive the below warning if you try to edit Virtual Machine properties, if Hardware version is 10 or more. Revert to previous snapshot, if you have taken snapshot before the VM hardware version upgrade. Create a New Virtual Machine with older hardware version and attach the disks from the existing Virtual Machine. Another method which is unsupported method. Simply editing the. VMX file of the virtual machine to downgrade the VM hardware version.
Let me explain this procedure in detail. Note: This is unsupported by VMware. Power off the Virtual Machine before editing the Configuration file of virtual machine. You can verify the current Virtual Machine hardware version from Virtual Machine configuration file. Edit the Virtual machine configuration file Vmname. Save the. Remove the Virtual Machine from vCenter inventory and register again. Thanks for Reading!!!. Be Social and Share it in social media, if you feel worth sharing it.

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.
You do have a few options to rollback and you find VMware KB , but none of them will work for you. The options located in the KB are:.
At the bottom of that same KB article, in the “Related Information” section, you’ll find that two other links:. It’s these links that provide another solution to do a VMware hardware compatibility downgrade for your VMs.
Danger: First, I can’t stress this enough. If you are here, that means that the options presented by VMware just won’t do it for you. Work on one 1 VM first to determine that this will work for you and take a snapshot, a backup of the VM, or an array snapshot before making any changes. Give yourself a way back so that if you make a mistake, you won’t have two issues that you’ll be dealing with instead of just the one.
Additional Information: My lab is running:. The table below shows valid values for the VMs I created in my lab but I went only as far back as being compatible with ESXi version 6. If you want a complete listing of version numbers, you can see this KB article Virtual machine hardware versions.
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. Here’s the command:. As cloud technologies and automation become first-class citizens within IT organizations, he desires to share everything he learns and pass it on to others.
Orange County, Tustin, CA The options located in the KB are: Revert to a snapshot. This is the easiest option but assumes you’ve taken a snapshot in the first place. 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.
