249 249  **Must I adopt semantic versioning rules when switching to SDMX 3.0?**
250 250  
251 251  No. If backwards compatibility with pre-existing tools and processes is required, then it is possible to continue using the previous versioning scheme (with up to two version parts MAJOR.MINOR). Semantic versioning is indicated only for those use cases where a proper artefact versioning is required. If versioning does not apply to some or all of your artefacts, then rather migrate to non-versioned SDMX 3.0 artefacts.

273 273  In practice, the migration approach will often mirror the way in which organisations have migrated between earlier SDMX versions. Rarely, the new data models used mixed SDMX standard versions in their dependencies, and if they did then standard conversions were put in place. A typical method is to first migrate the re-used artefacts from the previous SDMX version to SDMX 3.0 and while doing so to apply the appropriate new semantic version string. From that point onwards, you can enjoy the advantages of the new SDMX versioning features for all those artefacts that require appropriate versioning.
