Convert Hyper-V Gen1 to Gen2... is it easy?

Not to be rude @JaredBusch but did you read it?

Yes, you on the other hand, apparently did not.

Judging from the screenshot on the post I have to say it doesn't not look like conversion, but cloning instead

[DustinB3403]

Semantics aside, cloning tool or "creating a new boot disk" you still get the same end result.

A version 2 VM.

Glossing over shit is how people f[moderated] shit up.

If that is the only end result, then yes.
But the specific question was asked to "convert"

Cloning means you are duplicating space used. Converting will generally not.

Let's not get too technical.. My real question is the ability to expand/shrink on the fly/VM stay online. I know for a fact that Gen1 cannot do that.. thus the question about conversion.

But do you have teh space for two copies during the operation? That's a key piece of why it is important.

Good question... we are 60% of the disk at the moment... so that would be no. The space inside VM it self is 50% full.. Say 2TB disk space on hypervisor. the VM is uing 1.2TB. But the OS/Files is using only 600GB out of 1.2TB.
If the cloning means 100% identical then I will not have enough space. But if there is a way to shrink while cloning then it is a viable option.

See..... these things aren't details, they are super important.

This also means you're using thick provisioning.

Perhaps you can copy the current VM disk to another VM disk, but one that is thin provisioned. Then it will only take up 600 GB on the disk, leaving you with 2 GB free space until you delete the old VM disk.
