Some approaches to content demotion that have previously been proposed are considered to be unsafe. The content demotion approaches that should never be used include: - Removing every instance of the component from the International Edition (or source edition)
- This approach will delete the history of the component for users of the International Edition, who do not use the demoted content. The history of each SNOMED CT component should be traceable in the edition in which the component was created.
- Retaining the component active in the source module, and creating a new version of the component (i.e., with a more recent effectiveTime) in the less more dependent (extension) module
- This approach will make the component visible and accessible in the source edition, and users of the source edition would not be aware that the component was demoted to a less more dependent (extension) module
- This approach may lead to inconsistency between the version of the component in the International Edition and the version in the less more dependent (extension) module.
