16<p>The following pages describe how to upgrade applications coded against
17the Berkeley DB 1.85 and 1.86 release interfaces to the Berkeley DB 2.0 release
18interfaces.  They do not describe how to upgrade to the current Berkeley DB
19release interfaces.</p>
20<p>It is not difficult to upgrade Berkeley DB 1.85 applications to use the Berkeley DB
21version 2 library.  The Berkeley DB version 2 library has a Berkeley DB 1.85
22compatibility API, which you can use by either recompiling your
23application's source code or by relinking its object files against the
24version 2 library.  The underlying databases must be converted, however,
25as the Berkeley DB version 2 library has a different underlying database format.</p>
