I'm just completing a switch from MD600 to QNAP.

Do run the Sooloos Interrogator on your library before you start the transfer process. You can do this per store, so it doesn't matter if they are not both online at the same time. Also make sure that you rename the first output file from the Interrogator before running it a second time as it can overwrite.

Then once you've finished the restore onto QNAP you can run the Interrogator again to make sure that you are not missing any albums.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
