I have created a simple model to copy a feature dataset from one geodatabase to another. I want to feature dataset to overwrite an existing feature dataset. There are no locks on any data in either geodatabases. When I try to run the model I get Error 000260, which results in the feature dataset in the paste location to be deleted. However, when I manually run the Copy tool, I can copy the feature dataset without issue. Not sure why this is not working. Any help is appreciated.
