i'm not sure if 4.3.2 is even supported anymore. 4.3.3 has been withdrawn from release, but is, surprisingly still supported (at least for those willing to pay).
if you wanna know of a 4.3.3 maintenance level will work with your 4.3.2 level, you may want to try the install/update with preview mode (installp with -p option) to see what prerequisites are needed. i would assume that if it says nothing fails, then it's ok.
