We had someone upgrade their AIX 5.2 box from SP3 to SP4. A couple of
days later, he decided he needed to roll back to SP3. He came to us to
see if it was possible to do so, and pointed out that he had installed
the Service Pack in the APPLIED state (not COMMITTED).
However, when I took a look, I found that while some of the filesets
were APPLIED, others were COMMITTED. I looked around, but couldn't
find any way to roll back to SP3. Any ideas?
