Update Annotation Reference Scale (Cartography)—ArcGIS Pro

Summary

Updates the reference scale of an existing annotation or dimension feature class.

Before a feature class can have its reference scale updated, it must be upgraded to the current release using the Upgrade Dataset tool.

This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

Versioned feature classes cannot have their reference scale updated.
Changing the reference scale of a feature class is an intensive operation that requires an update of every feature's bounding box geometry.
An ArcGIS Desktop Standard or ArcGIS Desktop Advanced license is required to update the reference scale of a feature-linked annotation feature class.
