Thank you, for your replies. I guess I was not really clear with my 
question...let me be more clear this time.
   I have a really old server running in my lab and the aim was to 
install a new server and transfer all the contents to this new server. 
But since I am novice to the whole concept of AFS, I dont want to screw 
up things my moving volumes to the new server only to realize that I did 
something wrong in the process. I though that "copying" ( if such a 
thing exists) would be safer. But from the response of  Russ only one 
copy should exist on a cell so I am not really sure what to do.
    The old server is a file server which uses kerberos (KDC) for 
authentication. I have added the new server as an additional server to 
the cell to which the old server belongs. I am not sure if these are 
sufficient but in any case, I thank you all for the help.
