When you run the Import-CsPersistentChatData command to migrate the exported data to Microsoft Lync Server 2013 Persistent Chat server, the operation fails and you receive error messages that resemble the following:
Error: Unable to determine the identity of domain.
Error: An error occurred: "System.ObjectDisposedException" "Can not access a closed Stream."
This issue occurs because the input data size has exceeded the 10,000 item limitation.
