If you are using python, just create the new model and save it and the new table will be created and the information saved. Note, new tables are not created until something is saved in them. I assume the same works in java, but I have never used java on AppEngine.
From the documentation http://code.google.com/appengine/docs/python/datastore/overview.html:
Unlike relational databases, the App Engine datastore does not require that all entities of a given kind have the same properties. The application can specify and enforce its data model using libraries included with the SDK, or its own code.
So if you create new properties or tables, they are added, but only to the new entities you save, the old entities remain unchanged.
