at this moment im building a new Exchange organization for my client. its an exchange 2013 built on windows 2012 (Domain B)
the client has an old domain with exchange 2010 with users in it .(domain A)
i constructed a full trust between both domain which works fine so far.
what i was wondering about if there is a way to move all the users with their mail boxes from the old domain to the new domain via move requests or something.
is their a way to do that or this will be old fashion dirty moving on per user base from the client side.
