[cisco-voip] Patches, Upgrades, Service Releases.......

[Micah Bennett]

Ed/Scott

 

Thanks for the input.  

 

I talked with one of the TAC team yesterday and he helped me understand
the differences between the OS updates/patches and the Application OS
patches.  With that and your comments I feel a lot less confused now.  

 

I plan to implement the same type of plan that both of you mentioned.  

 

For the OS items, I will do them as they become available after I
research them.  Generally the feedback on these items has been that
there is little if any risk related to the applications other than a
server reboot. 

 

As for the Application patches, I will do them as needed for a bug fix
or feature update.  The whole reason any of this came up in the first
place is because we have a bug in CRS 4.05 that is fixed in CRS 4.05SR1.
Now that 4.05SR2 is released I am probably going to go on and do it
instead.  

 

Thanks again, with the group here, and the super TAC support I have been
getting on these issues, I have learned a lot this week. 

 

Have a good day.

Just to throw my 2 cents in with Scott, some suggestions,

- sign up for the update notification tool that Wes mentioned
- Make sure you're also on the security alert mailing list from cisco
also just in case, If i can remember when I went to sign up for that
I'll post it. 

>From my perspective, I have a maintenance window once a month to run
non-critical updates/patches. On the MCS server windows OS platforms I
check whats out there a few weeks in advance.. if there is an OS service
release I'll pencil it in for my window barring any major catastrophes
with it. I don't touch the actual UCCX / CER / CCM application service
releases or patches unless I have a specific reason to do so. If there
is a security patch out for OS or application that I feel we are exposed
to, that gets patched as soon as I can weasel some downtime for it.

We just upgraded to the appliance platform for CCM recently and I
haven't really formulated my own update strategy yet for that.. since
the OS and application updates are bundled. Still mulling that over but
I may opt for only as needed or dictated by security concerns.
