But noury you did not read well. I cannot change the byte-codes of the 
method  while loading
because this is the exact method that I'm modifying.

Here is what I wrote:

Move SystemChanges functionality from SystemDictionary to ChangeSet 
class
  Pay attention the two Changesets should be loaded one after the one. 
When loading them you will get a SystemChanges is still referenced. 
This is normal. We get rid of it after. So do not move it to Undeclared 
(I should retry because I always forget). Then you will have a 
deprecated method opening a debugger, proceed and the rest will work. 
You deserve an explanation: because this is a bit tricky. We cannot 
avoid that since we are modifying the system that produces the call to 
the deprecated method itself. During the load the method is changed to 
be deprecated, its callers too but the code currently executing the 
load is still the old one. When the changeset is loaded the old code is 
used. This is only at the end of the load that the new code is in place 
and that the next time the deprecated method won't be called again.

Send me a private email on that, because they are there, proceed the 
debugger and the changes are installed.

Please read all the previous thread on migrating KCP 3.5 to KCP 3.6.
because classes have been removed from the system in parallel to our 
refactoring.
