Format Migration

What is Format Migration?

Format migration is the process of converting digital records or documents from one file format to another to maintain their accessibility, usability and interpretability over time. It is commonly used when an existing format becomes obsolete, unsupported or unsuitable for long-term preservation.

Format migration is an important digital preservation strategy because changes in software, operating systems and technology can affect the ability to open or interpret older files. The process should preserve the content, structure and relevant metadata of the original record while documenting the conversion to support authenticity and traceability.

Key Features

• Format Conversion: Converts digital records from an existing format to a newer or more sustainable format.

• Preservation Planning: Identifies formats that may become obsolete or difficult to access.

• Content Preservation: Aims to maintain the information contained within the original record.

• Metadata Preservation: Retains relevant descriptive, technical and administrative metadata during conversion.

• Conversion Validation: Verifies that migrated files remain accessible and usable after conversion.

• Migration Documentation: Records details about the conversion process, source format and destination format.

Benefits

• Continued Accessibility: Helps ensure digital records remain accessible as technology changes.

• Reduced Obsolescence Risk: Reduces dependence on outdated or unsupported file formats.

• Long-Term Preservation: Supports continued usability of digital records throughout their required retention period.

• Improved Format Sustainability: Enables organizations to move records to formats better suited for long-term preservation.

• Maintained Record Context: Helps preserve relevant content and metadata during format changes.

• Better Preservation Governance: Creates a documented approach for managing format-related preservation risks.

Conclusion

Format migration helps organizations maintain access to digital records when existing file formats become obsolete, unsupported or unsuitable for long-term preservation. By carefully converting files while preserving their content, metadata and relevant documentation, organizations can reduce format obsolescence risks and support continued usability of digital records.
