<div>Thanks. I'm thinking edge first is a good idea too. <br>

<div>It really doesn’t matter other than the order in which it will impact your environment. The “cluster” isn’t a mesh replication like CUCM, it’s more of like a master slave relationship.

</div>
<div>In theory, you have the same license options on both cluster peers, so one peer can function in the same capacity as the other peer.<br>
<br>
<div>I would do the Edge first, then the control; especially if you have internal-only routing on the control server ... leave that for last.</div>

<div class="gmail_default" style="font-family:"trebuchet ms",sans-serif">I've never seen any documentation that is specific about shutdown order etc. There are also 3 different restart options for Expressway/VCS -- restart, reboot, or power down. There is also
series of guides for cluster maintenance under deployment guides, which may be helpful for you. <a href="https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-10/Cisco-Expressway-Cluster-Creation-and-Maintenance-Deployment-Guide-X8-10.pdf">https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-10/Cisco-Expressway-Cluster-Creation-and-Maintenance-Deployment-Guide-X8-10.pdf</a></div>

<div class="gmail_default" style="font-family:"trebuchet ms",sans-serif">Aside from upgrades, the few times I've had to do something like this was restarting Expressways to clear software errors. I did the primary, then secondary nodes once the primary was
back online. This is also the order suggested for upgrades. I personally do not see any value in doing one cluster before the other, but most of the deployments I see are the simple and supported ones. </div>

Just wondering what people are doing when they need to restart their expressway cluster? Since C is the one initiating the connection to E, and because the primary is reaching out to subscribers, I'm thinking:<br>
<br>
Shutdown Order<br>
<br>
C primary<br>
C subscribers<br>
E primary<br>
E subscribers<br>
<br>
(Re)Start Up Order<br>
<br>
E subscribers<br>
E primary<br>
C subscribers<br>
C primary<br>
<br>
Thoughts?<br>
