ArchiMate 4 replaced 3.2: how to migrate models without losing meaning

▤ Summary

This article explains how ArchiMate 4 changes the modeling framework from ArchiMate 3.2 and what that means for migration. It highlights the new domain structure, the expanded Common Domain metamodel, and revisions to specialization and multiplicity rules. It also notes that some concepts have moved or been renamed, so teams need to review model semantics carefully during upgrades. Readers working with enterprise architecture tooling should treat this as a standards update that may require model refactoring and validation.
