Using Python for batch updating datasources in multiple MXD files.
Over the past few years, I have often seen clients manually changing datasources in their MXD files. This typically needs to be done when copying MXD files from DEV to UAT, or UAT to PROD. Doing this manually is time consuming, so I put together a quick video showing how to do this using ArcPy. This is one way to batch update several MXD files in multiple folders at the same time: https://youtu.be/4dq_ApqFN-k
