I have a process where I had to make an update in production to change a variable from singular to multiple and deploy. If I go into the running instances, I'm not able to update variables. So, my question is this? How are they handled? Do they go on as they were in the process version they started on, or do they update all instances to the newer version. I'm guessing the first. Also, I can update any place where the elment is indicated in the running process instance to multiple, but if I can't update the variable, wouldn't I just be causing errors to update it every other AC location where it writes to it? Thanks for any feedback!...
