When I try to copy the entire feature dataset from the file geodatabase into the feature dataset in ArcSDE, I get the error: "Failed to paste. The operation is not supported by this implementation." When I try to copy the feature dataset into ArcSDE (outside the feature dataset), it copies everything but the geometric network and it copies everything to the root directory - not a feature dataset where I want it.
Again, there is nothing in the feature dataset that I'm trying to copy into, so there's no files to interfere. The feature dataset is a valid location because I can copy single feature classes to it. I just can't get that geometric network to copy.
I will try rebooting my machine and see if that helps.
