Backgrade/downgrade and database constraints

Can anyone point me to a document that clarifies which version changes make changes to the underlying data structure and would thus hinder or prevent a backgrade/downgrade without reverting to version-specific data backups?

The changelog isn't explicit on this subject and some changes suggest that backgrading might be awkward or impossible. Nowhere can I find this documented.

    I'm a fellow user.

    It is not documented anywhere, nor do I believe any testing is done on downgrades. It is not something I test, nor is it a level of compatibility I expect in software.

    The last major change to the the data structures was made in Moneydance 2015, so it is known it is not possible to downgrade from that or any later version to an earlier release.

    Since then the basic data structures have essentially remained unchanged but there have been detail changes in how various features work in the different versions since, which may or may not impact downgrading to an older version.

    The best policy is to assume you cannot downgrade.

    Thanks dwg, I appreciate the input.

    However I disagree in so far as, the BEST policy would be for Maddy or Ethan to raise an enhancement request to version the data structure separately to the application which would just be a process change going forward when documenting the changelog, not any coding.

    An acceptable interim policy is to assume one cannot downgrade.

    Thanks!
