This term is sometimes used to refer to the transfer of information to non-digital media.
Migration includes refreshing, that is, copying digital information without changing it.
However, while refreshing will overcome the problem of media instability, it usually isn't enough to keep abreast of technological obsolescence . Migration to new operating environments often means that the copy is not exactly the same as the original piece of information. Providing information about successive migrations in the form of metadata will assist in determining what changes have occurred to the digital object. The complexity of the migration process will depend on the nature of the digital resource which may vary from simple text to an interactive multimedia object. At its simplest, migration may entail copying digital information to a more stable non-digital medium, such as paper or microfilm.
