why  not to transfer roles while old DC are online?

why not simply add new DCs to current production domain?

I'm thinking about way to upgrade too, but using "separated environment" 
and restore current production servers from backups seems too 
complicated for me.
I don't know what changes was made in prodiction domain while doing 
procedure above, if it will take day or two (and it wiil be lost)

hmm :)
