If you mean the .rrd (or .log) files, then these are named according to the
Target name (ie, the thing in the [] in the .cfg files).  You can rename the
.cfg files to whatever you want without changing the historical data,
although you need to make sure your periodic task picks up the newly-renamed
files, especially if you are using a master.cfg file to include them all.

HOWEVER:
If you use the routers2.cgi frontend, there are a few caveats.
1) Your bookmarked URLs wil change, as these use the filename as a key.
2) If you are using graph archiving, then you will need to rename the
archive files for that config file.
3) If you are using rrd-archive then you are OK, these can cope with file
rename (but not targetname change).
4) You may need to change the cfgfiles directive in the routers2.conf if you
are not using the generic *.cfg

Some of this may also apply to 14all and mrtg-rrd, but you'll have to check
the docco for those if you use them.
