I have this note preserved, but I can't remember if I have actually used 
this procedure or whether I kept it "just in case":

cd /usr/local/var/rancid
echo "new_device_name:device_type:up" >> GROUP/router.db
cp -p CVS/GROUP/configs/old_device_name,v \
      CVS/GROUP/configs/new_device_name,v
cd GROUP
rm configs/old_device_name
cvs -d /usr/local/var/rancid/CVS update .

(The above instructions need some further testing; you may also be able to 
do (cd group; cvs update) too rather than the longer version)

Then let rancid run and learn the new device (don't forget to modify 
.clogin too). Once it is complete, remove the old name from router.db and 
rancid will clean up the data for the earlier name.
