Best practice for encrypted data migration to Windows 2012 file server

Hi,

I am looking for best practices to migrate Symantec encrypted data from one server to another.

Can someone point my in the direction of best practices for this?

Is it just simply creating a NetShare on the new file server, then robocopy the encrypted data from one NetShare to the other?

Is there anything I need to be wary of with de-duplication?

Thanks,

Michael
