+.. _upgrade4to5: Upgrading from RDFLib version 6 to 7
+
+============================================
+Upgrading 6 to 7
+============================================
+
+New behaviour for ``publicID`` in ``parse`` methods.
+----------------------------------------------------
+
+Before version 7, the ``publicID`` argument to the
+:meth:`~rdflib.graph.ConjunctiveGraph.parse` and
+:meth:`~rdflib.graph.Dataset.parse` methods was used as the name for the default
+graph, and triples from the default graph in a source were loaded into the graph
+named ``publicID``.
+
+In version 7, the ``publicID`` argument is only used as the base URI for relative
+URI resolution as defined in `IETF RFC 3986
+<https://datatracker.ietf.org/doc/html/rfc3986#section-5.1.4>`_.
+
+To accommodate this change, ensure that use of the ``publicID`` argument is
+consistent with the new behaviour.
+
+If you want to load triples from a format that does not support named graphs
+into a named graph, use the following code:
+
+.. code-block:: python
+    
+    from rdflib import ConjunctiveGraph
+
+    cg = ConjunctiveGraph()
+    cg.get_context("example:graph_name").parse("https://example.com/source.ttl", format="turtle")
+
+If you want to move triples from the default graph into a named graph, use the
+following code:
+
+.. code-block:: python
+
+    from rdflib import ConjunctiveGraph
+
+    cg = ConjunctiveGraph()
+    cg.parse("https://example.com/source.trig", format="trig")
+    destination_graph = cg.get_context("example:graph_name")
+    for triple in cg.default_context.triples((None, None, None)):
+        destination_graph.add(triple)
+        cg.default_context.remove(triple)
