<h1 class="topictitle1">Performing a Primary/Secondary Switchover for a Replication Consistency Group (Deprecated)</h1>

<div id="body8662426"><div class="section" id="evs_04_2056__en-us_topic_0079692996_section57480441"><h4 class="sectiontitle">Function</h4><p id="evs_04_2056__p4637150811111">This API is used to perform a primary/secondary switchover for a replication consistency group. A switchover can be performed to switch the primary and secondary AZs of a replication consistency group, which means that the original secondary AZ will be switched to function as the primary AZ, and original DR ECSs and DR disks will be enabled.</p>
|
|
<p id="evs_04_2056__p35078900163112">After the primary/secondary switchover, the <strong id="evs_04_2056__b842352706194243">replication_status</strong> value of the replication consistency group is <strong id="evs_04_2056__b84235270619437">active</strong>. At this time, the data between production disks and DR disks in the primary and secondary AZs is consistent in real time, and EVS replication is working normally.</p>
