Backup on Windows and Restore on Linux possible?

I decided to move my Windows-based Plex server to a Raspberry PI3 box, at least to test it out. However, I was wondering if it is possible to move the entire Windows server to Linux maybe through a backup or other procedure?

I tried copying the folders over using WinSCP but I got an error in the Linux log.

Anyone know if it is possible?

Thank you
