Will Hyper-V VM's work on new bare metal server

[Chrish1]

Hi,

I picked up a Poweredge R840 GPU ready ($499 Yay!) for my home server which will replace my existing Poweredge R830 running a handful of VM's on Hyper-V. My plan is to move the hard drives from my Poweredge R830 into the Poweredge R840. Since both servers are using a Perc H730 raid card so the drives should move nicely.
The VM's are Generation 2 9.0 Configuration and each VM is using TPM.

My question is, will the VM's work on new bare metal or does some sort of migration need to be performed due to the bare metal hardware change? VM drive location on the physical hard drives will not change.

Any advice is greatly appreciated.

TPM will be an issue, see here, they did a great job documenting the process:

It sounds like you got a great deal on that R840... Since both servers use the Perc H730 RAID card, your drives should transfer over without too much hassle. However, there are a few things to consider before you make the move...

1. TPM and Secure Boot Considerations – Since your VMs are Generation 2 and use TPM, you may run into issues if the new server doesn’t recognize the existing TPM configuration. You might need to disable TPM in the VM settings temporarily and then re-enable it after migration. Also, check if the TPM settings in the new BIOS/UEFI match your previous setup.
2. Driver & HAL Compatibility – Even though Hyper-V abstracts a lot of hardware, different CPUs, firmware versions, or chipset changes can sometimes cause issues. Make sure you update firmware, drivers, and Hyper-V integration services before the move.
3. Migration vs. Direct Transfer – While your VM storage paths remain the same, the host change means that Hyper-V will likely see these as new VM registrations. You may need to manually import the VMs using "Import Virtual Machine" in Hyper-V Manager, choosing the "Register in-place" option.
4. Backup & Test First – Before swapping drives, I’d recommend exporting one VM to an external location and testing the import process on the new server to ensure smooth compatibility.
