Dear Jianbo,
You may want to try one of these PDB-editing web servers:



Both make you choose the file before you can see the options, but can  
do several things, including changing chain ID and renumbering.  I  
haven't tried exactly what you describe, but it is probably worth  
trying before using a text editor.

I hope this helps,
