Preservation actions that results in changes to the file, such as migration, should be documented in a note element in accordance with DACS 7.1.4 See also RAD 9.8B10b. For example:
Electronic files migrated by National Data Conversion from the original word-processing software (WordStar for CP/M) to Wordstar 4.0 for DOS and to ASCII to maintain readability of data. Technical specifications are filed with media in Restricted Fragile.
Expanding on DACS 7.1.4, in an effort to be more transparent about the reproduction process, document refreshment or ingest into the local digital repository. For example:
Electronic files migrated by National Data Conversion from the original word-processing software (WordStar for CP/M) to Wordstar 4.0 for DOS and to ASCII to maintain readability of data. Wordstar 4.0 for DOS and ASCII files refreshed into the Yale University Library Rescue Repository. Technical specifications are filed with media in Restricted Fragile.
