Yes, log in as sys, update con$ set name = new_name where con# = (select con# from con$

                 where  owner = 'constraint_owner'
                 name = 'old_name')

There is a unique index i_con2 on con$ (con#) and a unique index i_con1 on (owner, name)

These cant be rebuild, they are part of instance warmstart, as you can se from bootstrap$

I have used this method on 8.1.7 without any negative impact. But only if the need is there and no other solution could be applied while 'business as usual' was ongoing.
