[cisco-voip] CM and Unity upgrade questions

[Rhodes, Geoff]

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.
