Q. Will I lose my MSDN and TechNet reputations?
A. Currently you can’t carry over your MSDN and TechNet reputation. We are working to give you the opportunity to link Microsoft Q&A and MSDN and TechNet forums. When this is an option, your current badges and points from MSDN and TechNet forums will be displayed as part of your Microsoft Q&A profile.

I also had the badges and points on Technet/MSDN forums and asked the same question here.
