<p>You will need to upgrade your on-disk databases, as all access method database formats changed in the Berkeley DB 2.0 release. For information on converting databases from Berkeley DB 1.85 to Berkeley DB 2.0, see the <a href="../api_reference/C/db_dump.html" class="olink">db_dump185 utility</a> and <a href="../api_reference/C/db_load.html" class="olink">db_load utility</a> documentation. As database environments did not exist prior to the 2.0 release, there is no question of upgrading existing database environments.</p>
