You can IIF the patchfile is created for the differences between your
current patch level and the new level.

for example patchfile.1 is created for the patch from version 2.1 to 2.2
            patchfile.2 is created for the patch from version 2.2 to 2.3
            patchfile.3 is created for the patch from version 2.1 to 2.3
If your system is at version 2.1 then there are 2 paths to go from 2.1
to 2.3
          2.1 --> patchfile.1 --> patchfile.2 --> 2.3
          2.1 --> patchfile.3 --> 2.3

The cumulative sum of the changes in .1 and .2 equal the sum of the
changes in .3.   In the example above it is impossible to go from 2.2 to
2.3 unless you use the patchfile.2 or you remove the effects of
patchfile.1 then apply patchfile.3.

ANY other path will usually fail.

Thus, it depends on the patchfile(s) being used on how you get from one
place to the other.
