Move all user setting
 

I have a new server ( host A ) and a existing server ( host B ) , I will move all data from host A to host B , could suggest what is the best method to move all the user data including /etc/passwd . /etc/shadow , /etc/group , ~userid/.bash_profile , /home , how to make the user can use the same password after move the server ? thx

Well more details on your setup would be nice. Are you planning to just copy them over the network, zip them up and put on media to place on new server? And don't copy the whole passwd and group files.. only copy the users from them to the new server.
