                <link>https://jira.mongodb.org/browse/SERVER-42411</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Dear Team,&lt;br/&gt;
Currently we are using MongoDB-3.4 as a standalone service in our Application and planning to migrate to MongoDB-4.0.&lt;br/&gt;
As per our understanding direct upgrade from 3.4 to 4.0 is not supported (As per the mongoDB documentation).&lt;/p&gt;

&lt;p&gt;Can we use below approach to avoid first upgrading to 3.6 and then to 4.0?&lt;/p&gt;

&lt;p&gt;Take backup of the data from 3.4 database using mongodump and then restore to 4.0 database using mongorestore&lt;br/&gt;
We tested this sample data and observed it is restoring fine in 4.0, however we are not sure whether this option can be considered in production environment.&lt;/p&gt;

&lt;p&gt;Thank you.&lt;/p&gt;</description>
