Exchange 2013 cross forest migration

Our current scenario is as below

domain: abc.logo
Primary: dc1.abc.logo
secondary: dc2.abc.logo
Exchange 2013: exch2013.abc.logo

domain: abc.com
primary: dc01.abc.com
secondary: dc02.abc.com
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.

So something like this is pretty envolved. High Level Steps are below...
- create forest trust to 2nd domain
- setup/configure ADMT (member server in source domain)
- migrate AD Objects to 2nd domain
- migrate mailboxes using Prepare-MoveRequest.ps1 script

You will have to use the prepare-moverequest script because the ADMT tool does not migrate Exchange attributes.
