In the syllabuses for SA5 and SA6 they both say they're leading on from ST5. Though SA5 also mentions ST9.
Personally I'm going to do ST5, ST9 and SA5 but as Edwin and others I know show, you could definitely get away with ST6, ST9 and SA5.
SA6 is directly related to investment advice, while ST6 is about pricing derivatives. They're in the same realm but not particularly linked. Someone with more experience could prove me wrong though.
Not that any of the exams are particularly easy, I think SA5 has a better reputation than SA6.
