Try optimising your index in 3.5 before migrating to 4.2, as this should
upgrade all segments to the 3.x format.
Note however, you are likely to find issues using an index from 1.4 in a
4.x system. You will have to maintain the old field definitions using
the old components, which will likely render some features
non-functioning.
For example, I have an index in that situation. My date fields were of
type DateField not TrieDateField, meaning I could not use them in boost
functions.
If you can, try to think of and plan a way to re-index your content.
