When I try to run the setup media to do an in-place upgrade from Windows Storage Server 2008 R2 Enterprise to Server 2012 R2 Standard the application will start then after copying temp files it gets to starting setup then crashes back to the install now screen. It does not give any error messages, I don't see any abnormalities in the event log either.
I have tried burning the ISO onto a USB drive and a CD but my NAS server does not detect the CD and says that I don't have permission to write to the USB device. I was able to burn the ISO from another computer and make the USB drive and CD available on the network so the NAS server could access it remotely but still same issue every time.
Any suggestions would be appreciated as I know 2008 Server is EOL and really need to get this upgraded ASAP.
Thank you in advance.
