The Annotation tool 
contains a selection tool and the Flip Annotation command 
that allow you to select an annotation feature and rotate it 180 degrees. This tool is available in the Modify Features pane.
When you flip annotation, consider the following:
- The annotation selection tool selects only annotation features and excludes other feature types from a selection.
- You can flip an annotation feature that is set to follow a feature.
- To prevent unintended rotation or scaling, uncheck the Enable rotate and resize check box.

To flip the direction of an annotation feature, complete the following steps:
- Add your data and configure settings for editing.
Confirm that the feature layer you are editing is editable, the coordinate system assigned to the active map is suitable for the type of edits you're performing, and snapping is configured to help you work efficiently and accurately.
Note:
To migrate annotation features from ArcMap, create a backup and upgrade the feature class. Similarly, you might need to upgrade annotation created in older versions of ArcGIS Pro. To learn more, see Manage annotation feature classes.
