Definition
In the context of data stewardship - the transfer of digital information to a new hardware (e.g. media) or software environment with the intent to preserve it. Migration is a means to overcome technological obsolescence and to exploit new technologies. The migration may or may not include a reorganization of the AIPs. A dataf ormat conversion is considered a reformatting, done as a reprocessing, and does not fall into the category of migration.
Comments
The transfer of digital information, while intending to preserve it, within the OAIS. It is distinguished from transfers in general by three attributes: • a focus on the preservation of the full information content; • a perspective that the new archival implementation of the information is a replacement for the old; and an understanding that full control and responsibility over all aspects of the transfer resides with the OAIS.
