Absolutely. It's a big job and hopefully you only do it once. Logically you have to then also think about your backup strategy to help prevent any re-ripping. Make sure you have that covered.

FWIW I keep a full clone of my MD600 on a NAS and also a full native export of the whole library on a USB twin drive.....and a recent clone of the library on spare HDD.

Cheers
