# Database Management

This section helps you repair sub-flow issues that can affect revision history and connectors.

The **Fix sub-flow's revision** and **Fix sub-flow's connectors** buttons are available in Leapwork Flow, under Settings and then **Database Management**.

* Use **Fix sub-flow's revision** history if you upgraded from an older Leapwork version and sub-flows fail because of revision history changes in the database.

* Use **Fix sub-flow's connectors**if you upgraded from an older Leapwork version and sub-flows show multiple input or output connectors because of revision history changes in the database.

**Note:**Database Management settings would be available if you are logged in as an administrator.
