Every workflow has a version number (this number must be an integer.)
Versioning allows you to run different versions of the same workflow simultaneously.
Use Case: A new version of your core workflow will add a capability that is required for veryImportantCustomer. However, otherVeryImportantCustomer will not be ready to implement this code for another 6 months.
Version 2 launch
Initially, both customers are on version 1 of the workflow.
- veryImportantCustomer may begin transitioning traffic onto version 2. Any tasks that remain unfinished on version 1 stay* on version 1.
- otherVeryImportantCustomer remains on version 1.
6 months later
- All veryImportantCustomer workflows are on version 2.
- otherVeryImportantCustomer may begin transitioning traffic onto version 2. Any tasks that remain unfinished on version 1 stay on version 1.
