[cisco-voip] CM and Unity upgrade questions

[Ryan Ratliff]

Speaking for the CM memory question all of 4.x requires the same  
amount of memory.

Upgrading CM, especially from 4.1(2) to 4.1(3) will be a relatively  
painless process.  Just make sure you have a good BARS backup of your  
publisher before proceeding (as is always the case with any upgrade).

For the CM OS 2000.4.3a and 2000.4.2 appear to be getting updated at  
the same time but unless there are servers supported on 4.2 and not  
on 4.3a I'm not quite sure why honestly.  Maybe Wes could speak to  
that.    Usually the reason for a new OS version is because of new  
servers that require the updated platform configuration disk.

Please excuse the newb questions, I'm sure they've been asked too many
times already.

Call Manager OS Release
We are on OS Release 2000.4.2sr10 and as of yesterday I see that the
most current versions are 2000.4.2sr12 and 2000.4.3a.sr5.  I assume I
upgrade to the 4.2 release, but can anyone explain what the differences
are in the two?


Call Manager
We are running version 4.1(2)es40.  It looks like the latest version is
4.1(3)sr3c.  I see discussions on here that 4.1(3) requires some
additional memory on the Call Manager servers (we currently run 1 gig on
each).  How easy is the upgrade (not including the memory upgrade)?
I've done several OS Release upgrades and a Unity upgrade, but upgrading
CM makes me a little nervous.  Does anyone have a "best practices" list
that you all do when performing an upgrade to CM?

Unity
Running 4.1(1) and 4.2(1) is out.  Anyone have any problems upgrading?
Are there "best practices" for upgrading Unity also?

Again, I apologize for the simple questions and appreciate everyone's
comments in advance.
