Should I validate the source VM before starting a large V2V conversion?
Posted: Thu Aug 27, 2026 6:50 am
Hi everyone,
I’m planning a V2V migration of several VMs and want to avoid discovering disk or boot issues only after the conversion has completed.
The current VM is about 480 GB, uses UEFI, has 3 virtual disks, and runs on ESXi 8.0. The target will be Hyper-V Gen 2.
Before starting the conversion, what checks do you recommend for:
disk integrity and unused space;
EFI/boot configuration;
partition alignment;
installed VMware Tools or drivers;
network adapter changes after migration?
For a VM of this size, would you perform any additional validation or create a test conversion first? I’m particularly interested in a practical pre-migration checklist that can reduce the risk of a successful conversion followed by a non-booting VM.
Thanks!
