+ <title>Upgrading Evergreen to 2.1</title>\r
+ <abstract>\r
+ <para>This Chapter will explain the step-by-step process of upgrading <application>Evergreen\r
+ </application> to 2.1, including steps to upgrade <application>OpenSRF</application>. Before \r
+ upgrading, it is important to carefully plan an upgrade strategy to minimize system downtime and \r
+ service interruptions. All of the steps in this chapter are to be completed from the command line.</para>\r

+ <para>Evergreen 2.0 has several software requirements:</para>\r
+ <itemizedlist>\r
+ <listitem>PostgreSQL: Version 9.0 is the minimum supported version of PostgreSQL. </listitem>\r
+ <listitem>Linux: Evergreen 2.0 has been tested on Debian Squeeze (6.0) and Ubuntu Lucid Lynx (10.04). If you are running an older version of \r
+ these distributions, you may want to upgrade before installing Evergreen 2.1. For instructions on upgrading these distributions, visit the \r
+ <ulink url="http://www.debian.org/releases/squeeze/">Debian</ulink> or <ulink url="https://help.ubuntu.com/community/LucidUpgrades">Ubuntu</ulink> websites.</listitem>\r

+ <para>To switch from the <systemitem class="username">root</systemitem> user to a different user, issue the <command>su - [user]</command> command; for example, \r
