hi guys quick query on hyper v , one of our guys created new vms for 2019 with gen1, instead of gen2, looking online at mbr2gpt etc anyone have a way they have used to get these vms to gen2, with the least pain possible

they're in production now so its not as easy just to wipe them and start again, saw links for john howard powershell but link no longer works

Any advice appreciated : )

    Hi,

    Generally, I will tell you it's not supported to convert Gen1 VM to Gen2 VM. Please rebuild the VM.

    But if you really want to know how to convert Gen1 VM to Gen2, you may refer to the following link. However, as noted in the artilce "it’s pretty in-depth and not for the feint-hearted to try."

    Good luck!

    Thanks for your time!
    Best Regards,
    Anne
