lyx2lyx also has the framework in place to be able to convert documents

lyx2lyx that can read documents in 1.5.x format. LyX 1.5.x can also

- Inset encodings and Conversion from earlier LyX versions
As part of the transition to unicode, lyx2lyx (the scripts used for converting
back and forth between different versions of the lyx files) converts old .lyx

After much deliberation, it was decided not to change older files such that
they will still reflect the old LaTeX output; rather, they will now correctly
reflect the situation as it appears in the GUI. This means, however, that if
