Set-AddressBookPolicy "AIG ABP" -OfflineAddressBook "EX13 Migration OAB"

Remove-OfflineAddressBook "AIG OAL"

3. Create a new Offline address book
New-OfflineAddressBook -Name "AIG OAL" -AddressLists "AIG GAL"

  1. Move the Mailboxes and data from 2010 to 2013 using the Microsoft standard practices
  2. Setup Pools and Plans in EPS for Exchange 2013
  3. Use the EPS Tool to migrate the users in EPS - this will tell our system which pools and plans the users are on when they are tagged as being on 2013.  There is a full document on how to do this in the Docs/Migration folder called EPS Migration Guide
