            <title>[DOCS-5587] Comment on: &quot;manual/tutorial/split-chunks-in-sharded-cluster.txt&quot;</title>
                <link>https://jira.mongodb.org/browse/DOCS-5587</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;This statement is extremely hopeful as I contemplate converting a big replica set into a sharded DB:&lt;/p&gt;

&lt;p&gt;&quot;When you shard a collection that has existing data, MongoDB automatically creates chunks to evenly distribute the collection&quot;&lt;/p&gt;

&lt;p&gt;However, it doesn&apos;t give me any idea how it does this.  So I&apos;m not sure how confident I should be with its technique.&lt;/p&gt;

&lt;p&gt;The only things I&apos;ve found that seem relevant to my challenge suggest somewhat involved approaches to pre-splitting data (&lt;a href=&quot;http://stackoverflow.com/questions/19672302/how-to-programatically-pre-split-a-guid-based-shard-key-with-mongodb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://stackoverflow.com/questions/19672302/how-to-programatically-pre-split-a-guid-based-shard-key-with-mongodb&lt;/a&gt;).  If the above statement is telling me what I hope it is then my strategy would be to create a new sharded cluster in which my original replica set is one shard.  Then I would drain that shard.  But that goes against what this page says:&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;http://docs.mongodb.org/manual/tutorial/remove-shards-from-cluster/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/tutorial/remove-shards-from-cluster/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;&quot;This procedure describes how to safely remove a single shard. Do not use this procedure to migrate an entire cluster to new hardware.&quot;&lt;/p&gt;

&lt;p&gt;Now, I think I understand the intent there.  But there&apos;s room for different interpretations.&lt;/p&gt;

&lt;p&gt;This is close:&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;http://docs.mongodb.org/manual/tutorial/convert-replica-set-to-replicated-shard-cluster/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/tutorial/convert-replica-set-to-replicated-shard-cluster/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;But again, it isn&apos;t a complete statement.&lt;/p&gt;</description>
