When a marketing associate needs to make changes to an existing journey in Salesforce Marketing Cloud, such as reordering the emails it contains, the recommended approach is to create a new version of the journey.
This feature allows for modifications to be made while preserving the original journey structure and performance data. Creating a new journey version enables the associate to make necessary adjustments, test the changes, and then activate the new version without disrupting the existing journey's flow or performance.
This method ensures a smooth transition and allows for comparison between different journey versions, facilitating continuous improvement and optimization.
