"Careful" means exactly that. A simple "portupgrade -a" *may* work
for you, as it has certainly done for others. However, there is
plenty of complementary evidence that the exact same command line
operation, with a different set of ports installed, results in a
smoldering heap of instability, broken-ness, plague, locusts,
spontaneous combustion, and other side effects.
We have 15k+ ports. On multiple architectures. On multiple
different OS revisions. As such, the likely number of all possible
combinations of the above rapidly approaches the number of atoms in
the (known) Universe.
In such cases, it is simply easier to write "carefully", than attempt
(and fail) to enumerate every single combination. It is (was) a big
change. If you (generic) are at all unsure, don't rely on automated
upgrade systems, particularly on mission-critical machines.
