# Editing a process instance in progress

If necessary, a process can be changed when it has started instances. In this case all started instances will be affected.

## Adding steps

* If new step will be added to process, in the active instances it will just be added into proper place:

![](/files/667e32974ef6a1ec50cf4d77a971015088734134)

![](/files/efeda3fc2dd43cefa2dd48a9034ceb3e147f580a)

* In the completed instances the new step also will become completed:

## Deleting steps

![](/files/c9dcfb26a549890784726967134fbd140e348ddc)

* If there are no instances that have this step active and the next path is unambiguous, step will just be deleted.
* If deletion of the step will cause instance to get another step active, the system will ask user for active step re-assigning (3) when process will be saved. User must select another step to make it active (4):

* After this, deleted step will disappear from all instances and newly assigned step will become active:
