Maintaining a digital object in a usable state over time is a crucial aspect of digital preservation. Existing methods of preserving have many drawbacks. This paper describes advanced techniques of data migration which can be used to support preservation more accurately and cost effectively.To ensure that preserved works can be rendered on current computer systems over time, "traditional migration" has been used to convert data into current formats. As the new format becomes obsolete another conversion is performed, etcetera. Traditional migration has many inherent problems as errors during transformation propagate throughout future transformations.CAMiLEON's software longevity principles can be applied to a migration strategy, offering improvements over traditional migration. This new approach is named "Migration on Request." Migration on Request shifts the burden of preservation onto a single tool, which is maintained over time. Always returning to the original format enables potential errors to be significantly reduced.
