I have the following scenario for a 2-server FS system with failover
functionality:<br>
<ul>
<li>I have a number of Gateways registered at FS1</li>
<li>I have another number of Gateways registered at FS2</li>
<li>In case I want to do maintenance on FS1 I would like all external
gateways to be registered on FS2 and then shutdown FS1<br>
</li>
<li>This is not of a problem if I have only a handful of gateways,
but in our case they're about 10.000<br>
</li>
<li>The goal is to minimze downtime, when I migrate e.g. 5000
gateways from FS1 to FS2</li>
</ul>
<ul>
<li>1st method: The normal way would be to register (via xml-rpc or
socket) the new Gateway on FS2 and then deregister it on FS1. FS1 sends
an unregister (register with expires=0) to the gateway though (after
the register from FS2), so this Gateway unfortunately no longer sends
calls to any of the 2 FS.</li>
<li>2nd method: The other way is to deregister them first on FS1 and
then register them all on FS2. Because deregistering and registering
takes time with ~5000 Gateways (+ we have to ensure that the new
register has to take place after unregister), this results in a
significant downtime.</li>
</ul>
So my question: Is there any way to suppress deregister messages to the
gateway?<br>
<br>
Best regards<br>
