How workbooks, data sources, extracts and Prep flows behave when Tableau Desktop, Tableau Prep Builder and Tableau Server run different versions: publishing and downloading rules, downgrading workbooks, Prep Conductor's incompatible-feature behaviour, and the Prep version-number format before 2022.3.

- Exam section: Migration & Upgrade

**Official exam objective:**

> 5.4 Understand backwards compatibility

## What the exam expects

- Predict whether a workbook or data source can be published, downloaded and opened when Desktop and Server versions differ.
- Downgrade a workbook with Export As Version, a versioned download or publication-time downgrade, and know what downgrading removes.
- Explain what an older Desktop can do with a data source published on a newer Server.
- Predict what happens to a Prep flow whose features the Server does not support.
- Read Prep Builder and Desktop version numbers from before and after the 2022.3 alignment.

Key terms:
- **Release upgrade:** a new major version such as 2022.1 or 2022.3; compatibility issues usually arise between these, not between maintenance releases.
- **Maintenance release:** a numbered update inside a release, such as the first fix release after 2022.1.
- **Downgrade:** saving a workbook for an older Tableau version; features the older version lacks are removed.
- **Export As Version:** the Desktop File menu command that downgrades a workbook.
- **Tableau Prep Conductor:** the Data Management capability that schedules and runs flows on Tableau Server.
