Duranta Erecta winter care

Anyone have any experience with the Duranta?
I found little info out there and even that is mixed.
Some say to overwinter indoors, with proper light, some say to overwinter outside.
But living in a zone 7, I have serious doubts it will make it through the first day of winter.
So I intend to winter it indoors, with a proper light setup, the same I use for portulacaria and other trees I keep indoors.
Any thoughts?

I see that it is listed as USDA zone 10 or 11 which generally do not see freezing temperatures. I would definitely protect it from frost and am guessing that frost is apt to cause major damage to the tree.

Yes, outside is out of the question. Just unsure if to green house it, or keep it indoors like a portulacaria.
