It is relatively trivial to upgrade from 1.0 to 1.1 and 1.2 is as far as you need to go to be able to use a more modern PHP. The biggest changes are how the controller interacts with the model and views, which can be done with a sed script in most instances. Most plugins for 1.2 offer versions for both Prototype and jQuery. In general, Symfony 1.* was easier to work with than 2.0. Symfony 2.0 feels very much like a Java project in that they prefer mounds of configuration files, reflection, annotations, etc, all to do something very simple - routing and view management.
