[cisco-voip] Upgrading CallManager to 4.X

[Lelio Fulgenzi]

We'll be looking at upgrading from 3.3(3)sr4a to 4.1(2) as well. I'm eager to heare from anyone that has done something similar.

>From what I've gathered, we'll have to be more worried about what happens after the upgrade then the actual upgrade itself. By this I mean the changes that come along with v4.x. For example, directory numbers are now it's own object, and deleting a phone does not delete the directory numbers associated with that phone -> that's an administration change that has to take place.. Another example is that voicemail ports are handled differently and there are steps to take before and after the upgrade to ensure voicemail access works properly. Those are just two that I've noticed - changes to the phone , animated icons etc, will also have to be properly advertised to clients.

Since each version lists the 'new features' seperately, it will be important to become familiar with the release notes for 4.0(1), 4.0(2) and 4.1(2). 

And of course, testing things in a test environment is key.

  Subject: [cisco-voip] Upgrading CallManager to 4.X


  Currently have a Pub and Sub running 3.3.3SR4a

  I'm replacing the Publisher with a more redundant server and want to
  upgrade to 4.X while I'm taking the downtime.

  Has anyone performed this upgrade.  Are there any GOTCHAS! I should be
  looking for?
  The instructions are basically:
  1) Backup the server, uninstall CAR
  2) Build the new server, Install 3.3
  3) Restore the config from the old server
  4) Upgrade to 4.X

  Which version should I be aiming for.  I've seen 4.0X as well as 4.1X
  Can anyone share their experiences with the group?
  Thanks in advance,

  -=Vandy=-
