It depends. I've never had to crate another breed forever, but my one basenji would get destructive if left alone.. the 2nd one would pee on my bed. So crating it was. However, I'm home so they were rarely crated. My current basenji is fine loose as long as she's alone. So like they said, do it slow, confine to an area that is safe and see how it works out. But if you need to keep crating, most dogs sleep far more than people.. up to 17 hrs a day. Just exercise before and lots after so they aren't bored.
