<p>Content pass: encyclopedic seed/expansion</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Format migration&#039;&#039;&#039; is the preservation strategy of converting digital objects from obsolete or risky file formats into newer or more open ones so content remains renderable. It contrasts with [[Emulation (computing)|emulation]], which keeps the original bytes and recreates the old environment.<br /> <br /> ==Trade-offs==<br /> Migration can lose features (macros, layout, proprietary metadata) and must be documented to preserve authenticity. Institutions often migrate in generations—e.g. from ageing office formats to PDF/A or other stewardship formats—guided by format registries.<br /> <br /> ==See also==<br /> * [[Digital preservation]]<br /> * [[File format obsolescence]]<br /> * [[Born-digital]]<br /> <br /> ==Sources==<br /> * Digital preservation textbooks and national-library guidance.<br /> * Format registry documentation (PRONOM and similar).<br /> <br /> [[Category:Digital preservation]]<br /> [[Category:Concepts]]</div>
