inplace upgrade hyper-v-server 2012 to 2016

Troubles –>
Core 2012 R2 to Core 2016:

• Create directory c:\logs (give any name, actually) for setup logs
• Before upgrade, uninstall antivirus, if you are using one on the server
• .\setup /compat ignorewarning /copylogs c:\logs
• If, during setup you get a blank blue screen, stop setup (click red ‚X‘ on setup output screen) and look into c:\logs\Panther\ActionableReport.html file for errors.
• fix errors
• Restart setup. Always use ’start from the beginning‘ option, never ‚continue previous‘ installation.
