Our current scenario is as below
Exchange 2013: exch2013.abc.logo
New Exchange 2013: exchange2013.abc.com
We need to migrate exch2013.abc.logo to new exchange2013.abc.com and then need to decommission of current exch2013.abc.logo.
We assume that we will need to do cross forest exchange migration by creating trust between two domain and usign ADMT tool for the users and mailbox migration.
Kindly suggest the best practises or steps or referance links.
