ArcCatalog has a useful Set Data Source tool which allows for rapidly updating multiple data sources in a map document that have changed.

Is there a similar functionality in ArcGIS Pro for project files, or within a project?

I can presumably also script a solution like Repairing data sources in multiple MXDs using ArcPy?, but not all our team members have the same skill level.

You can do this with ArcPy and a few lines of code.

import arcpy
aprx = arcpy.mp.ArcGISProject(r'C:\Projects\YosemiteNP\Yosemite.aprx')

The code above is from Updating and Fixing Datasets.


For me at least the ArcPy solution didn't work (it ran, but nothing changed). There is a (rather cumbersome) process using the Catalog View in ArcGIS Pro. It's documented here: https://pro.arcgis.com/en/pro-app/latest/help/projects/update-data-sources.htm

This only kind of worked for me (3.0.1); my layers remained broken, but then when I fixed one of them manually, the rest all got fixed too.
