Manoj, If you change your dfs.name.dir (Which is the right property for 0.20.x/1.x) or dfs.namenode.name.dir (Which is the right property for 0.23/2.x) completely to a different directory, you will need to move the contents of the original, older name-directory to the new one to preserve data, or if you wish to start again from scratch, you'll need to run a format of the NameNode and scrub your DataNode directories clean.
