@Jim Wooldridge Understood.  We didn't do this in production, but in-place upgrades have been a handy for us to update our dev environments without having to move VMs around and needing additional hardware.

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.

I understand the value here for sure.

The latest download for Hyper-V Server on the Eval site is 17763 (1809). Does anyone know when Hyper-V Server 1903 (18362) might be release? I would really like to use FoD 1903.

Highlighted

@kgncc Microsoft Hyper-V Server is part of the Long-Term Servicing Channel (LTSC). It only releases when we release the LTSC version of Windows Server, every 2-3 years. 1903 was a Semi-Annual Channel release, so there is no 1903 version of stand-alone Hyper-V Server.

@Jim Wooldridge If upgrades are not supported in any way, why is it even an option on the installer? Shouldnt it only allow clean installs?

Highlighted

@Jim Wooldridge 

 

I have tried both options in the installation UI of Hyper-V Server 2019: Either keep files (which I guess means upgrade) or delete all files (which I guess means clean install).  Either way, the installation fails and automatically reverts back to the original Hyper-V Server 2016 that I had running before trying the installation.  Currently, if I simply run setup.exe without any arguments, there is no way I can install Hyper-V Server 2019 on a machine running Hyper-V Server 2016.  Also, I would like to comment that the new setup UI leaves a vast amount to be desired.  The "clean install" options claims that it will delete all files, but it does not.  I also didn't see a way to specify the installation location.

Highlighted

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.

@Mary Hoffman 

Not being able to inplace upgrade to Hyper-V Server 2019 would not be an issue if after a clean install it would be easy to reapply configurations to the new Host.

Neither the less, it would be an appreciated feature in future Hyper-V Server Releases.

 

Thanks for taking this to the feature list.
