Thanks for the link, however the proposed method of moving triples from one graph to another assumes that the user wants to move all the triples from one graph to another. In my case I just need to move a particular subset of triples from one graph to another. Also, it seems to be an overkill to remove triples from the database and re-insert them when I just need to be changing their graph parameter. Do you think I could use the tip give over here [1] with an additional where clause to specify the triples?

You can use SPARQL 1.1 Update syntax to source triples from one Named Graph IRI that are INSERTED into another. <http://vocab.deri.ie/pdo> <http://open.vocab.org/terms/defines> ?s.
