hernummering

Hernummering, or renumbering, is the process of assigning new identifiers to items within a catalog, database, or inventory. It is typically undertaken after organizational changes such as restructuring, merging multiple catalogs, standardizing a numbering scheme, or accommodating growth. The goal is to establish a clear, scalable, and consistent set of numbers that reduces ambiguity and simplifies maintenance.

The renumbering process usually includes designing a new numbering scheme, generating a mapping from old to new identifiers, and implementing the change in the information system. Often, old numbers are preserved as secondary references or aliases to maintain traceability, while users and systems are redirected to the new numbers. Documentation and communication are important to avoid confusion among users who rely on the identifiers.

Key considerations include data integrity, backward compatibility, and the potential impact on external integrations, references, and workflows. A migration plan typically involves testing, staging, and a controlled rollout, with an audit trail that records the changes and the rationale for them.

Variants of renumbering range from full renumbering of all items to partial renumbering of selected groups. Some schemes distinguish hierarchical or semantic components (for example, category and item numbers) to support future growth. While renumbering can improve organization and standardization, it carries risks of broken links and misidentification unless carefully managed.
