MicrosoftMicrosoft Hyper-V Server 2019 is live on the Microsoft Evaluation Center!!

Also live on Visual Studio Subscriptions on 6/19/19: https://my.visualstudio.com/Downloads?q=Microsoft%20Hyper-V%20Server%202...
In the interest of saving everyone's valuable time, it appears that Hyper-V Server 2019 no longer provides the ability to perform an in-place upgrade. Additionally running setup.exe on an existing Hyper-V Server (checked with 2012 R2 and 2016) and performing either of the setup options (upgrade or clean install) will result in a failed installation. Just tested these options with the latest ISO (17763.737.190906-2324.rs5_release_svc_refresh_SERVERHYPERCORE_OEM_x64FRE_en-us_1.ISO as of writing).
The only way to install Hyper-V Server 2019 is to boot from the ISO and perform a clean install.
It'd be nice if Microsoft documented this somewhere, especially as it's a behavioural change from past releases.

Thanks for reporting this. We're investigating the issue.
- Any update on in-place upgrade?

kamalswami Please refer to Jim Wooldridge's response on this thread from July: "Hyper-V Server upgrades aren't officially supported (nor has the validation of upgrades of various configurations of Hyper-V Server been conducted). Point well made that the install experience should handle and communicate this better. I can put upgrades on the potential feature list for future versions, but I do want to be clear that this isn't supported." Hyper-V is only released along with our LTSC versions so a new version is not expected in the short-term. At this point, we are still investigating options.
