As database environments did not exist prior to the 2.0 release, there is no question of upgrading existing database environments. <table><tr><td><br></td><td width="1%"><a href="../../ref/upgrade.2.0/convert.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/upgrade.3.0/intro.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> </body> </html>
