Hello
I need to upgrade some Servers 2012 R2 to server 2016. I should to this Silent, for this I use a unattend.xml and start the script as follow
setup.exe /unattend:unattend.xml
Put I recive allways an Errot
This upgrade path is not supported. Please close Setup and re-launch from the root of the media or go back and pick a different installation choice
When I start the setup.exe without the unattend Parameter I can upgrade. When I use the same unattend.xml for 2012R2 upgrade I works fine.
I have read somewhere that the Parameter /unattend for the W2k16 setup do not work. Is thet true? And how can I make a Silent upgrade to a W2k16 Server?
Andreas
