[cisco-voip] Comments on Call Manager Upgrade Plan (My firstupgrade)

[Jeff Ruttman]

Hello Dave,
 
I did a pub and 2 subs.  The pub took an hour and a half, and I had one
period where I waited 20 minutes for an update to the update log.  The
subs took about an hour.  I did the installs on both subs concurrently,
and then I rebooted one, and after it had settled, rebooted the other.  
 
A couple of our phone models got new firmware with the new CM version,
and most of them did not upgrade without a power off and back on, so I
had to hunt them to their port on a switch and do a shut/noshut.  Total
phones weren't so many for me, but if your upgrade will also update
firmware and you have a lot of phones, that could certainly increase the
time you'll need if your phones act like mine.  If you have lots that
will upgrade, you might want to upgrade the phones before you do the CM
upgrade.
 
I did a lot of testing too.
 
All told it took about 4 hours for me.
 
Thanks
jeff

	Greetings,
	 
	I see by the Cisco Alert at the very end of this email that I'll
have to do my first CCM upgrade this weekend--or bust!  I have a few
questions from the OS Admin Guide and a couple more in my "upgrade
plan.'  Not a major upgrade; I'm upgrading from 6.1.2 to 6.1.4(SU1).
Any comments will be appreciated greatly.
	
	


I am going to be doing a similar 6.1(2)su1 to 6.1(4a) upgrade in a week
or so as well.  Is there a normal per server time that the upgrade takes
to apply (from the point in OS admin where one specs the upgrade file to
the time you are asked if you want to reboot to the new partition)?

I have two clusters of 4 7835s each to upgrade and I want to get a feel
for the maintenance window I'll need.

Thanks!!!
