I am not an expert but I would say the exams don't get upgraded.
A while after JDK 5.0 has appeared the corresponding SCJP exam also appears. And that is SCJP 5.0. The old exam for SCJP 1.4 is still available.
There's another thing called "Upgrade Exam" but it is for people who let's say have the SCJP 1.4 already taken and want to just get tested on the differences between 5.0 and 1.4 so that they can also get the SCJP 5.0 title. This way they take a "smaller" exam (than the full one for 5.0) but also get the title SCJP 5.0.
