How many active versions can a journey have at one time?

A journey in Salesforce Marketing Cloud can have only one active version at any given time. This is important for ensuring that the customer experience is consistent and that all participants in the journey follow the same interactions and paths. When changes are made to a journey, a new version can be created, but only one version can be executed simultaneously to prevent confusion and maintain clarity in the marketing efforts.

Having a single active version helps marketers effectively test and optimize their journeys without the complexity that comes from having multiple versions live at once. This single-version model also simplifies tracking results and measuring success, as all data and interactions are consolidated under one journey. If a marketer wishes to implement changes or improvements, they can deactivate the current version and activate the new one, ensuring a smooth transition without having conflicting paths for customers.
