            <title>[SERVER-17861] Change the default storage engine to wiredTiger</title>
                <link>https://jira.mongodb.org/browse/SERVER-17861</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;A proposal for handling users upgrading from 3.x to 3.2:&lt;br/&gt;
If a mongod is started without &lt;tt&gt;&amp;#45;&amp;#45;storageEngine&lt;/tt&gt; and the &lt;tt&gt;storage.bson&lt;/tt&gt; file in the dbpath indicates mmapv1, then set the global storage engine as mmapv1. Otherwise, set the global storage engine as wiredTiger.&lt;/p&gt;

&lt;p&gt;A proposal for handling users upgrading from 2.6 to 3.2:&lt;br/&gt;
If a mongod is started without &lt;tt&gt;&amp;#45;&amp;#45;storageEngine&lt;/tt&gt; and the &lt;tt&gt;local.ns&lt;/tt&gt; file exists in the dbpath, then set the global storage engine as mmapv1. Otherwise, set the global storage engine as wiredTiger. This allows users to upgrade directly from 2.6 to 3.2, even though the storage.bson file would not exist.&lt;/p&gt;</description>

&lt;p&gt;WiredTiger is used as the default storage engine if the dbpath does&lt;br/&gt;
not contain any data files. Otherwise, the storage engine specified&lt;br/&gt;
in the storage.bson metadata file is used when the --storageEngine&lt;br/&gt;
flag is omitted from the command line invocation.&lt;br/&gt;
