17. The information contained in an original document or a copy that must be retained for evidential purposes may be transferred to another medium based on a different technology.
However, subject to section 20, in order for the source document to be destroyed and replaced by the document resulting from the transfer without compromising legal value, the transfer must be documented so that it may be shown, if need be, that the resulting document contains the same information as the source document and that its integrity is ensured.
Transfer documentation must include a reference to the original format of the source document, the transfer process used and the guarantees it purports to offer, according to the specifications provided with the product, as regards the integrity of the source document, if it is not destroyed, and the integrity of the resulting document.
The documentation, including that pertaining to any previous transfer, must be retained throughout the life cycle of the resulting document. The documentation may be attached, directly or by reference, to the resulting document, to its structuring elements or to the medium.
