This section is for those test script developers who have quite a few test scripts already written in Selenium 1, also known as Selenium RC, and are planning to move to WebDriver. Moving entirely to WebDriver is a good idea theoretically, but when it comes to migrating the test scripts, it is a task that is going to keep you busy for a while, depending on how abstract your current test scripts are.
