OP
The data from the Vault can be transferred to any HD. I did this several years ago with the help of an IT guy. He had to make a call to Bluesound as the process wasn’t intuitive.
I didn’t scrub the Vault and left it connected to my LAN by Ethernet. Although the files from the Vault now reside on my Melco server, some of my streamers recognize the Vault as an accessory HD and the files play.
