Can I work with an Harmony 17 file with older versions?

I’m trying Harmony 17, but in my job they’re using Harmony 12. Can I work on 17 and be opened in an older version?

You can load a V12 scene in Harmony 17 but not the other way around.
Harmony 12 will not understand the changes and new features which
have changed the project structure from V17.

Thanks!
