I assume you mean the extrinsic IDs assigned by the resource. Note
that if you directly use EcoreUtil.Copier it's a map from old to new and
that you can use eObject.eResource(), cast it to an XMLResource, and use
getID. If you put the copies into a new resource, you can use that to
assign the same ID as it had in the old resource.

This works:

UMLResource res = (UMLResource) resourceSet.getResource(URI.createFileURI("NPModel.uml"), true);
JsonResource resource = (JsonResource) resourceSet.createResource(URI.createURI("generated/diagram.json"));
res.getAllContents().forEachRemaining(eObject -> resource.setID(eObject, res.getID(eObject)));
resource.getContents().addAll(res.getContents());
