Question : Forest Migration

Hi,
we have one forest with AD server abc.com and  backup AD. also we have one standalone exchange 2003 server. sub domain 2003 sub.abc.com with exchange 2003.
we need to migrate this forest to 2008 and exchange 2010 we have new hardware for this but I am not sure from wear I should start and how!
Is there any down time? Can I migrate one site only? what about Ips?

Answer : Forest Migration

I'm sure there is... but as I stated, it's not reasonable.  How could you do it?  As I told someone else asking a question of a similar nature, hire a programmer/hacker who can analyze how Windows does the upgrade to 32 bit, what calls it makes, and so-on and so-forth, and eventually, I'm sure they'll figure out a way.  It may costs 5 or 6 figures... but if you've got the money, nothing is impossible.

Put simply, as others and myself have stated in one way or another - and I'll restate for a second time in this comment - there is NO REASONABLE way of doing this.  That is your answer.  No reasonable technician (as I would define them) would spend any significant time trying to do this so it's HIGHLY unlikely you'll find ANYONE, especially anyone here, who has found a way of doing it - reasonable or otherwise.  Experts-Exchange is a great place to find answers to questions and problems that impact a business or your ability to use a system.  When you want to do something that no one thinks is a good idea or even possible, you'll almost certainly not find an answer you're satisfied with even when the answers provided are, lacking further evidence to the contrary, 100% accurate.
