Migrate Cifs to a Windows Server

Hello, 

We are currently researching how to migrate our current Netapp Cifs environment to a Windows 2012 Distributed File Services environment. I was looking to see if anyone has done this in the past and can provide any experience as to best practice or gotcha's. We are trying to determine if there is any ability to setup replication of some sort from the Netapp Cifs environment to the Windows server or if everything simply has to be copied via a tool like RoboCopy in one fell swoop. If there is anyone who can provide any insight into this topic, I would greatly appreciate it. We are running on a Netapp FAS 2240-2 with 7-mode 8.2.3 P6.

Thanks in advance.

Jeff
