                <link>https://jira.mongodb.org/browse/COMPASS-7500</link>
                <project id="13182" key="COMPASS">Compass </project>
                    <description>
    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;p&gt;    a new command &quot;moveCollection&quot; will be introduced in this project that will allow users to move unsharded collections to a shard of their choice one at a time in an online manner. &lt;/p&gt;

&lt;p&gt;we will deprecate movePrimary in favor of the moveCollection command. &lt;/p&gt;

&lt;p&gt;We would like to create a shell helper for moveCollection command. &lt;/p&gt;

    &lt;div class=&quot;panel&quot; style=&quot;background-color: #e3fcf7;border-color: #00684a;border-style: solid;border-width: 2px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 2px;border-bottom-style: solid;border-bottom-color: #00684a;background-color: #00684a;&quot;&gt;&lt;b&gt;Epic Summary&lt;/b&gt;&lt;/div&gt;&lt;/div&gt;
&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;

&lt;p&gt;Allow users to move an unsharded collection to a shard of their choice using moveCollection command without impacting their application&apos;s availability.&#160;&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;Motivation&lt;/h4&gt;

&lt;p&gt;All unsharded collections currently reside on the primary shard of a database. The ability to move an unsharded collection to any shard unlocks users&apos; ability to leverage horizontal scalability without needing to actually shard their collections. Most of our users have only 1 sharded collection. The primary shard has the most amount of collections and it would be good to move collections around without needing to shard them.&#160;&lt;/p&gt;
