I've prepared a journey which is around 15 days long. Now I want to do some modification in the same.
What happens to contacts which are there in journey (older version), if I simply go and activate new version and don't do any change in older version. Does sfmc flush out all contacts in older version at the time of activation of new version or they will still go through remaining journey.
What happens to contacts in older version, if I stop older version and then activate new version?
