You have to extract the graph you want and upload it to the new dataset.

The SPARQL protocol has no operations that span 2 different datasets.

i have a large tdb stored dataset with multiple graphs. can i move one
graph from one to another dataset? what would be the command using http
protokoll?
thank you!
