We're in the process of upgrading ESXi from an older version that only supported BIOS boot mode and I've got some questions around Windows Images (wim files) that we've captured from those VM's that are running on the older version of ESXi and what happens when I upgrade and my VM's start running under UEFI mode.
As we're still in the planning stage, mainly I'm looking for some general advice and guidance on how best to make use of these images in WDS once the migration is complete. I suppose the first question I have is whether or not these images will even be usable once the upgrade is complete - will images captured on VM's running in BIOS mode still be usable and deployable to VM's running in EFI mode?
And if not, what's the process to get them running again? Is there a way to convert those images work with UEFI mode or would they have to be rebuilt from scratch?
Thanks in advance!
Changing your host is not going to change your virtual machines. They are not going to change from BIOS to UEFI because the host has changed.
