Instead, standing up a new installation with a fresh MS SQL waiting for a database and attaching the backup to the database means you don't have to worry about any wonkiness that might occur due to the conversion from Hyper-V to VMWare.
This has issues of its own to deal with. Because there are a lot of ancillary bits to most MS SQL (or any SQL really) deployments that are not part of a database backup.
Yeah while true, anyone who is setting up this database system should be able to account for these issues as they are a part of the "installation process".
Rather than some random bug or crash due to a registry entry that decided to go haywire in the middle of a production day.

Not to mention the amount of downtime required to convert the working system to the VMWare standard. Which may not be acceptable for the business.
This downtime will, likely, not be particularly different than the offline time to backup, transfer, and restore a 1TB database.
I was simply accounting for the OS size as an additional amount rather than creating a new system with a SQL system ready to receive a database.

Actually, no. Because these types of things are usually, setup once 5 years ago with vendor support, type scenarios.
Rather than some random bug or crash due to a registry entry that decided to go haywire in the middle of a production day.
It is a V2V, nothing is happening in production.

I like to lean on the "you have support for your production systems, right?!" argument. . . .
And it would be production if it was powered on and running for a while with entries being written etc that are no longer on the hyper-v installation.
I've seen weirdness (Hyper-v 2008 specifically) that VM's migrated had a lot of remanent hyper-v drivers and registry entries that have caused issues.
Are you saying you've not seen these?

Hyper-V 2008 was a horrible platform. Everyone knows it.

Yea, but we can't say for certain he doesn't have an old hypervisor, nor the potential for weird bugs either during a conversion process.

You have a comprehension problem.

We are going from Hyper-V 2012 to VMware vSphere 6.5U2

Yeah, that was almost unusable.
