Migrating 10.3.9 to 10.3.9

I am trying to migrate 10.3.9 from a G4 system to an XServe system. I find that when I try to clone or image the G4 I get "/usr/sbin/named-checkzone: input/output error". The G4 server is working fine despite the error condition, and clones seem to work as well. Should I just not worry about the error (not my first choice)? I have run Disk Utility, fsck, plutil and Tech Tools and have not been able to correct the problem. Can I just delete this directory and replace it completely from a good source (or do I have some configurations in here I don’t want to lose)? Would it be quicker/smarter just to build a good system and then copy over the netinfo db? Appreciate your input.
