work folders prerequisites

dear All,

I need to implement work folder in my work place but i saw some doc said i need AD running windows 2012R and some said no need! by the way below is my environment:

1. AD running windows server 2008 R2

2. File Server Running windows server 2012 R2,

If AD need to be windows 2012 R2, Can i deploy additional domain control 2012 R2 for this deployment. 

Thank in advance

BR,
