Microsoftif you open the script you will see that missing .msi file is least of the problems with HA deployment. all the arguments are different from previous scripts and even having msi will not work with old instructions.. they did not update documentation for this release. don't think it will support direct upgrade as it is very different setup. It would be great if upgrade was possible but i think it will not work.
MicrosoftUpgrading directly from Windows Admin Center 2311 to Windows Admin Center 2511 in an HA configuration is unfortunately not supported due to backend breaking changes that occurred in 2410 with our .NET upgrade.
We apologize for the inconvenience the script has caused and we're working diligently to update it (and the documentation). When the new version is available, I will update this blog with a notice.
