[ciscozest]

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).

Need to upgrade to CM 4.1(3) and Unity 4.1(1) using New Hardware.
Current user data on both CCM and Unity must be retained.

Can anyone advice me the correct migration steps for CCM and Unity?
  Thanks
