How to migrate all users to an new server

I found the way to migrate all unix accounts, samba accounts and configuration from the old samba file server to new one. It is simple, justcopy the following files from the old filer server, then replace at the new file server: /etc/passwd (User name and account info) /etc/shadow (Passwords) /etc/group (Group names and membership) /etc/gshadow - Contains group encrypted passwords. /etc/samba/* /var/lib/samba/* After copying completion, restart the following services service smbd restart service nmbd restart Then all users login to new file server and share the files
