One of our customer raised the below query.


They have migration plan for a cross forest Lync 2013 to Skype Online migration, 




-Forest A has the Lync 2013 users with their SIP address set to

-All users are being moved to a new forest, which will have Office 365 with AADC

-New forest will have their SIP changed to a different domain i.e.




How the Lync accounts can be migrated to Skype online and preserve the contacts and chats?

Any pointers would be of great help. Many thanks.
