Replace file share server with a new one

view story

http://serverfault.com – I have a server, used for applications, with the path: \\cifs_server\folder I have to move it to a new server : \\cifs_server_new\folder (both folders has been synced). What's the best method for doing that, with the smallest interrupt of service? Change all the application's paths to the share (which can be long, IIS with lot of virtual directories) In host file, create an entry "IP_OF_NEW_SERVER cifs_server" (but will AD authentication still work? Remove *cifs_server* from domain, rename *cifs_server_new* to *cifs_server* and join it to domain? Thanks in advance ! Regards EDI (HowTos)
