Hello I recently acquired a EMC NX440.  This device has Windows Storage Server 2016 as the OS.  I would like to upgrade/update the OS.  How does one get WSS 2019?  Has anyone done a custom install of Windows Server on this device?  I would like to do a custom install Windows 2022.  This would be minimal install.  The device has 8GB of RAM with 6TB of disk space.  

Any input is appreciated.
