My question, to which I dont have an answer but i'm sure someone else on the list does: is there any ramifications to running different OS levels across your cluster during your upgrade process (assuming several days to update all the nodes in your systems then at 1 per day)
<br><br>Also, which server is your TFTP server, or do you have several. not sure how much of the phones configurations they store incase they cant talk to a service.<br><br>Personally, i'd be just waiting for the rest of the cluster to implode that same day... murphies law and all that :)

<div><font size="2">Just wondering if anyone has tried updating the O/S on a
subscriber during business hours, obviously after stopping the CallManager
service and forcing phones to register to another subscriber first. </font><font size="2">Our goal is to try an minimize the amount of after hours work that is
involved in maintaining this new fancy system of ours. </font></div>

<div><font size="2">Ideally, we'd see the following happening:</font></div>
<ul>
<li><font size="2">stop callmanager services and have phones register to another

<li><font size="2">start callmanager services during a short maintenance
window</font></li></ul>
<div><font size="2">Some questions:</font></div>
<ul>
<li><font size="2">are there any other services we should stop to make this as
transparent as possible?</font></li>

callmanager in line?</font></li></ul>
