[cisco-voip] Fw: Need Advice on CCM and Unity Upgrade steps:

[Lelio Fulgenzi]

i think you missed a step. you have to make a backup of your existing system using the latest BARS tool in order to be safe. this way if you have to restore from backup, it will be compatible with the copy of BARS on 4.1(3). something to remember as well is that MLA is not backed up with BARS - you have to back it up (and restore it) seperately.

  Hi,

  Please correct me if I am still wrong. thanks
    CallManager upgrade steps:
      1.. Uninstall existing BARS software 
      2.. upgrade to version 3.3(5). 
      3.. upgrade OS to 2000.4.2 with latest sr 
      4.. upgrade to version 4.1(3) 
      5.. Install with BARS 4.0(9) 
      6.. backup CCM 4.1(3) config to remote drive 
      7.. restore BARS to new CM 4.1(3) on the new hardware
  All our unity servers are Voice messaging only.
  Unity Upgrade Path:
      1.. upgrade Unity TSP to version 8.0(1) which is compatible with CCM 4.1(3) - new H/W servers and then test 
      2.. upgrade unity to version 4.0(4) 
      3.. upgrade to unity version 4.1(1) 
      4.. Install Dirt and back up to remote drive 
      5.. restore unity to the new H/W server running Unity 4.1(1).
  How to ensure that all phone setting and content of vm will be retained after the upgrade? Any idea? Thank you

  Where is the step where you upgrade from 3.3(5) to 4.1(3)?  Remember  
  you can't take a backup at 3.3(5) and restore it on to 4.1(3).
