My 5 yr old process now has 7 different versions, all of which have active instances. I have a need to make a few code changes in some succeeding rules, but need to make it apply to all versions.

Is there any way to directly modify the code without causing havoc?

If I could force an error in the succeeding rule of an activity then I would have access to the code to modify it (for that process version). My destination rules read a db to get the destination user, so I can put a bogus userid in the db and when K2 tries to send it's client notification email it will throw an error.  But how can I force an error in the succeeding rule? I'm using Infopath ... could I do something there that would force an error in a succeeding rule?

I have developed and tested my new succeeding rule code block in my development environment, and need to apply that specific block of code to all production versions. Could I do a sql update, setting the _code value = to the value in the dev _code table?

Thanks for any help you all can give me.
