I have been editing an existing Spatial ETL tool that loads a Feature class from a GDB, then uses transformers to match a schema in an existing GDB. I am migrating from one schema to an updated schema, basically. When I open up workbench (by clicking "edit" on an existing ETL tool) and run the tool, it works, but when I double click on the tool in ArcMap, it throws the error (Output staging Geodatabase already exists.). Any help would be greatly appreciated. I'm wondering if there is an "overwrite" option? Maybe my "Writer Feature" needs to be non existing, so that it doesn't "already exist"...I don't know.
