Multiple versions on PC

All,

I'm planning on installing 2012 PR1 on the same PC that I am currently running 2011 SP4.0 and I have some questions I hope can be answered.

  1. Can 2012 PR1 use my existing install of 2011 SP4.0 SNL?
  2. Can 2012 PR1 use my existing install of 2011 SP4.0 WPDM?
  3. What things should I be aware of before running two different versions on the same PC?
  4. I'm not concerned with using production data on PR1.

Thanks
