OVN tries the best to keep the DB schemas backward compatible. + +However, there can be situations that an incompatible change is reasonble. An +example of such case is to add constraints in the table to ensure correctness. +If there were already data that violates the new constraints got added somehow, +it will result in DB upgrade failures. In this case, user should manually +correct data using ovn-nbctl (for north-bound DB) or ovn-sbctl (for south- +bound DB), and then upgrade again following previous steps.
