Hi all. I am new to Unraid and I currently have a Windows 10 machine with a Storage Spaces parity setup. I use it for my Plex server. I was wondering the simplest way to transfer all the media over to the Unraid server? Would it be fastest to just create a simple two-disk Unraid server and transfer it over that way? Or is there a different solution? I was also wondering if I should use rsync or not during the transfer as I have heard that some files get skipped occasionally when transferring large amounts of data.
