For DirSync i understand perfectly, and i will deploy Password sync. What i have or i do not find is information, whether i could use or deploy new Exchange 2007 server. Move users that will need to go to different O365 tenant to that Exchange 2007 server. On that Exchange 2007 server activate Outlook Anywhere, with some public url and trusted certificate. And then activate Stage migration where migration endpoint will be that Exchange 2007 server.
Problem that I'm facing is, that i have Hybrid Exchange 2010 server whit by default is not supported scenario. BUT if endpoint and mailboxes exist on Exchange 2007 , that in theory shod not be a problem.
Or should it be ?
