Can I convert OS model version 2.4.3 backward to 2.4.0? I built a rather complex geometry I would like to keep instead of starting from scratch on an older version.

The 'hacky' (and probably only) way to back-convert is to open the osm in a text editor and change the Version Identifier in the OS:Version object at the top of the file to the previous version.

This will cause problems if the later OS version has added/changed objects that exist in your model, so it's best to not try to go back too far. Going from 2.4.3 to 2.4.0 might be ok, but be warned. Make a backup!
