<p>Using the forwarding topology created in <a href="rzahymasterfwd.htm#rzahymasterfwd">Create a master-forwarder-replica topology</a>,
|
||
|
|
you can promote a server to be a peer. In this example you are going to promote
|
||
|
|
the replica (server3) to be a peer to the master server (server1).</p>
|
||
|
|
<ol type="1">
|
||
|
|
<li>Connect Web Administration to the master (server1).</li>

<li>Expand the Replication management category in the navigation area and

click <span class="bold">Manage topology</span>.</li>

<li>Select the subtree that you want to replicate and click <span class="bold">Show topology</span>.</li>

the same procedure to create server5. The server roles are represented by

server1, it now needs to become a supplier to server1, server2, and server4.
