What is the next step to configure the New CIFS server in order to make changes invisible for hosts and users so they can continue using the CIFS via new NetApp without changing any mapping and etc. ( I know I have to make some changes in CIFSSetup.cfg&nbsp; and other CIFS config files but dont know the exact process)</P><P></P><P>2. for mapping mirrored LUNs from new NetApp to servers and un mapping the old LUNs&nbsp; , what is the best practice.</P><P></P><P>Thanks </P></BODY></HTML> Thu, 05 Jun 2025 06:15:56 GMT https://community.netapp.com/t5/Network-and-Storage-Protocols/CIFS-Migration/m-p/47862#M4368 ALENDPR_NETAPP 2025-06-05T06:15:56Z Re: CIFS Migration https://community.netapp.com/t5/Network-and-Storage-Protocols/CIFS-Migration/m-p/47867#M4369 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P></P><P>CIFS protocol is a session oriented protocol so I believe it is impossible to do it with out down time.
