win 2003 AD + Exchanage 2003 to Win2012 AD + exchange 2012
Current environment.:
windows 2003 functional domain level AD.
2 windows 2003 AD servers
1 exchange 2003 server.
1 windows 2008 R2 member server
I need to plan out to migrate this to windows 2012 servers.
Do I migrate exchange first to 2010 >2013, then migrate domain or migrate domain first?
Is it better to create AD at win2012 level, then manually build up AD or migration from 2003 to 2012?
Can you give me steps if you have gone through this similar setup?

After that, if I want to raise functional level to 2008 or 2012 and demoting 2003 DC, how exchange 2003 will react to it?
Are two above possible?
Also, running domain server or exchange server on hyper-v virtual machine compared to running on physical machine, how much performance do I expect to lose?
