            <title>[DOCS-15881] Some missing info re: M -&gt; N shard migrations</title>
                <link>https://jira.mongodb.org/browse/DOCS-15881</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;Was recently discussing limitations of M-&amp;gt;N shard migrations with &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=kai.orend%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;kai.orend@mongodb.com&quot;&gt;kai.orend@mongodb.com&lt;/a&gt;, and we realized that the docs don&apos;t seem to note the prohibition on reversing a M-&amp;gt;N shard migration (or, more generally, &lt;em&gt;any&lt;/em&gt; unlike-topology migration).&lt;/p&gt;

&lt;p&gt;Additionally, I noticed a tiny spot on &lt;a href=&quot;https://www.mongodb.com/docs/cluster-to-cluster-sync/current/multiple-mongosyncs/#configure-multiple-mongosync-instances&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this page&lt;/a&gt; that looks like it is out of date as of REP-160!&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;The source cluster and destination cluster must have the same number of shards.&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;cc &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=tim.fogarty%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;tim.fogarty@mongodb.com&quot;&gt;tim.fogarty@mongodb.com&lt;/a&gt; as well for visibility&lt;/p&gt;</description>
