            <title>[SERVER-69933] Allow change stream to survive movePrimary</title>
                <link>https://jira.mongodb.org/browse/SERVER-69933</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;At present, the &lt;tt&gt;movePrimary&lt;/tt&gt; command will cause a single-collection change stream to be invalidated, because the operation ends by dropping the collection on the original shard. Instead, the stream should be able to continue reading events from the collection after it has been moved to the new shard. This will require the &lt;tt&gt;drop&lt;/tt&gt; event to be marked as &lt;tt&gt;fromMigrate:true&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt;Additionally, the UUID of the collection on the new shard will be different than on the original (see &lt;a href=&quot;https://github.com/mongodb/mongo/blob/1d61d0b76ec6b6c130d6d2433d56df5524a7a82c/src/mongo/db/cloner.cpp#L396-L400&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this comment&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-32847&quot; title=&quot;Make copyDb transfer over UUIDs when it is called in metadataOnly mode&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-32847&quot;&gt;&lt;del&gt;SERVER-32847&lt;/del&gt;&lt;/a&gt;). This should be changed so that the UUID remains consistent throughout.&lt;/p&gt;</description>
