Is it possible to restore the data when a config file was renamed and you still have the old rrd's?

Yes, but you will also have to rename the corresponding xml file. The paths are: ...just rename them appropriately and the perfdata will go to the new host/service name.


For future ref, if you have XI Enterprise Edition, the easy way to do this is go to:
Configure -> CCM -> Tools -> Renaming Tool -- here you can rename hosts/services and keep their performance data
