Hello and thanks for peeking into this topic!
We have few AD's and 1 2010 Exchange server and we would like to migrate/consolidate all the AD's and move the 2010 exchange to 2013.
Whats been done so far.
New AD , New 2013 Exchange , Two way trust etc.
We've been able to migrate users with ADMT and Move mailboxes from 2010 to 2013, however we would like to still somehow use AD(1,2) and slowly migrate all of it to ADNew that comes along with mailboxes.
So is it the best way to do that with relay?
Exchange2010 - source
Exchange2013 - target
Someone sends email to cute@domain.com > Cute user does only exist on NewAD > Exchange 2010 forwards email to 2013?
Someone sends email to cute2@domain.com > Cute2 user exists on OldAD1 > Exchanges2010 accepts email and puts it in the Cute2 mailbox :)
Is that my best option ?
