This post was originally published on this site

Hi All,


I am trying to upgrade windows server 2008 r2 to windows server 2012 r2. its a vcenter vm coverted from physical server.


the problem im experiencing is when i run the installer for windows server 2012 r2, it gives an error on lsi adapter, ultra320 scsi 2000 series is not compatible. i have tried to remove the driver from device manager and after reboot it comes back. I have deleted the sys file, which fails the os to boot up again and fails with blue screen.


i’m using vmware vcenter 6.7.
