      <description>&lt;P&gt;Hi&amp;nbsp;&lt;a href="https://communities.vmware.com/t5/user/viewprofilepage/user-id/5449573"&gt;@MyJourney&lt;/a&gt;&amp;nbsp;,&lt;/P&gt;&lt;P&gt;If the ESXi management network and the VMs are still using the vDS, you will have issues removing the host from vDS. To avoid resulting the host in a partial state or loosing connectivity, please refer following options:&lt;/P&gt;&lt;P&gt;1. Place the host in maintenance mode and migrate all VMs from it before removing the host from vDS. Ensure that the hosts management network is moved to a standard switch before removal.&lt;/P&gt;&lt;P&gt;OR&lt;/P&gt;&lt;P&gt;2. Create a standard switch --&amp;gt; Migrate management network to it --&amp;gt; Migrate VMs to standard VM port groups&lt;/P&gt;&lt;P&gt;Hope that helps&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi &lt;a href="https://communities.vmware.com/t5/user/viewprofilepage/user-id/5449573"&gt;@MyJourney&lt;/a&gt;,&lt;/P&gt;&lt;P&gt;&lt;SPAN class="VIiyi"&gt;&lt;SPAN class="JLqJ4b ChMk0b"&gt;&lt;SPAN&gt;To remove a host from a vDS, first&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/SPAN&gt; you have configured a different switch for the hosts.&amp;nbsp; I&lt;SPAN class="VIiyi"&gt;&lt;SPAN class="JLqJ4b ChMk0b C1N51c"&gt;&lt;SPAN&gt;t is NOT necessary to put the host into maintenance mode.. &lt;SPAN class="JLqJ4b ChMk0b"&gt;It is recommended if you have DRS enabled so that the VMs are automatically migrated to other hosts&lt;/SPAN&gt;.&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN class="VIiyi"&gt;&lt;SPAN class="JLqJ4b ChMk0b C1N51c"&gt;&lt;SPAN&gt;&lt;SPAN class="JLqJ4b ChMk0b"&gt;Yes you have to take into account the following&lt;/SPAN&gt;:&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;UL class="ul"&gt;&lt;LI&gt;Verify that physical NICs on the target hosts are migrated to a different switch.&lt;/LI&gt;&lt;LI&gt;Verify that VMkernel adapters on the hosts are migrated to a different switch.&lt;/LI&gt;&lt;LI&gt;Verify that virtual machine network adapters are migrated to a different switch.&lt;/LI&gt;&lt;/UL&gt;&lt;P&gt;&lt;SPAN class="VIiyi"&gt;&lt;SPAN class="JLqJ4b ChMk0b"&gt;&lt;SPAN&gt;Once this is verified, you can remove the host from vDS at any times.&lt;BR /&gt;&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN class="VIiyi"&gt;&lt;SPAN class="JLqJ4b ChMk0b"&gt;&lt;SPAN&gt;Regards,&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN class="VIiyi"&gt;&lt;SPAN class="JLqJ4b ChMk0b"&gt;&lt;SPAN&gt;Ulises&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/SPAN&gt;&lt;/P&gt;</description>
