Most common commercial 9L0-402 products today provide utilities for backward compatibility and for swapping documents, databases, and more complex objects between software systems. Although this strategy simplifies migration and may lower digital preservation costs by reducing the amount of customized reformatting needed as technology changes, it does not eliminate the need for regular migration of digital materials. Software and standards both continue to evolve and even repositories with structurally homogeneous holdings can expect to be required to migrate their digital materials periodically.
Current methods fall far short of what is required to preserve digital materials. All current preservation methods involve 9L0-509 trade- offs between what is desirable from the standpoint of functionality, dependability, and cost and what is possible and affordable with current technologies and methods.
