5.1 DIGITAL MIGRATION

Digital Migration is defined to be 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 intended for preservation;

– a perspective that the new archival implementation of the information is a replacement for the old; and

– full control and responsibility over all aspects of the transfer resides with the OAIS.

It should be noted that ‘transfer’ as found in the definition of Digital Migration is used in a broad way such that when any changes are made to Content Information or to PDI bits for the purpose of information preservation, then this is a Digital Migration even if it appears the changes occurred ‘in place’.
