Well if you read the manuals it says that this can't be done.  The reason
for that is that the context files use the name of the host for their context
and it is difficult and dangerous to start swapping it around.  I have done
this before and yes it can be done but you have to be careful and be
prepared for grief.  Here is what you do:

Make a complete backup of everything.
Edit the /etc/clusterconf file to reflect the new names
     (note once you do this you better not reboot because the system
    won't come up properly until it we fix all the cdfs)
run a shell script which searches for every cdf with the context of the old
name and change it to the new name.  It would look something like:
    find . -hidden -type H -name ${oldname} -exec mv {} ${newname} \;

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Note that is a guess please verify with the manual before you use it!.

then reboot the server and look around to see if everything is okay.
