            <title>[DOCS-14336] Rename ReplicaSet</title>
                <link>https://jira.mongodb.org/browse/DOCS-14336</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;
&lt;p&gt;Hi!&lt;/p&gt;

&lt;p&gt;I have a replica set of three nodes, and I want rename it.&lt;/p&gt;

&lt;p&gt;The documentation &lt;a href=&quot;https://docs.mongodb.com/manual/tutorial/rename-unsharded-replica-set/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/tutorial/rename-unsharded-replica-set/&lt;/a&gt; says that in order to rename a replica set I have to:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;make a backup,&lt;/li&gt;
	&lt;li&gt;stop all nodes of the replica set,&lt;/li&gt;
	&lt;li&gt;change the name of the replica set to mongod.conf (I&apos;m using a configuration file),&lt;/li&gt;
	&lt;li&gt;enable them without a replica set,&lt;/li&gt;
	&lt;li&gt;change the name of the replica set in the locale database,&lt;/li&gt;
	&lt;li&gt;enable all nodes again as a replica set.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;The backup is needed as insurance against incorrect actions when renaming a replica set.&lt;br/&gt;
Then I can do this:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Change the replica set name in the configuration file,&lt;/li&gt;
	&lt;li&gt;Change the replica set name in the locale base on each node sequentially,&lt;/li&gt;
	&lt;li&gt;Turn off successively the secondary nodes,&lt;/li&gt;
	&lt;li&gt;Restart the primary node,&lt;/li&gt;
	&lt;li&gt;Turn on the secondaries of the node in sequence.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;During times 1 and 2, the set is available for writing and reading. At time 3, it is read-only. i tested this on 4.2+&#160;versions with C# driver.&lt;/p&gt;

&lt;p&gt;This way, I minimize the time the replica set is unavailable until the restart time of the two nodes.&lt;/p&gt;

&lt;p&gt;Why is my varinat dangerous? What problems can arise if you do this?&lt;/p&gt;

&lt;h2&gt;&lt;a name=&quot;Scopeofchanges&quot;&gt;&lt;/a&gt;Scope of changes&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;ImpacttoOtherDocs&quot;&gt;&lt;/a&gt;Impact to Other Docs&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;MVP%28WorkandDate%29&quot;&gt;&lt;/a&gt;MVP (Work and Date)&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;Resources%28ScopeorDesignDocs%2CInvision%2Cetc.%29&quot;&gt;&lt;/a&gt;Resources (Scope or Design Docs, Invision, etc.)&lt;/h2&gt;
