Downgrading Unity Express from 3.0.1 to 2.3.2

Answered Question
Nov 28th, 2007

Hi, i have a problem downgrading Unity Express from 3.0.1 to 2.3.2 Actually the customer has an Unified Communicator version 4.3(1)sr1 and following the compatibility matrix i will need CUE version 2.3.2 but i receive a NM-CUE with CUE 3.0.1 and it is not compatibility.

Well i think it will be easy to make a downgrade to CUE 2.3.2 , i have downloaded all the archives that i started the boot helper program successfully but when i want to load the package cue-vm.2.3.2.pkg it appears the following error:

Please select from the following

1 Install software

2 Reload module

3 Disk cleanup

(Type '?' at any time for help)

Choice: 1

Package name: cue-vm.2.3.2.pkg

Server url: ftp://192.168.1.64/

Username: anonymous

Password:

Downloading cue-vm.2.3.2.pkg

Bytes downloaded : 137065

Validating package signature ... error

Package signature validation failed for pkg cue-vm.2.3.2.pkg

Unable to install. Please try again

Please select from the following

1 Install software

2 Reload module

3 Disk cleanup

(Type '?' at any time for help)

Please i need a hand with this, only just in case i am using Vista as a FTP server, just in case.

Thanks in advanced ...

I don't think that's available. It's basically a clean install. If possible, I'd use the online installer (software install clean...) method. If not, then try using the 3.0 installer image (from the TFTP server). I know it seems backwards, but the problem is that the 2.3 installer probably can't handle the post-3.0 upgraded system.

Correct Answer by craiglcve about 9 years 2 weeks ago

could you try running the install software clean command?

software install clean url ftp://X.X.X.X/cue31/cue-vm-k9.nm-aim.X.pkg

The X's are the ip address and the cue pkg name.

Hope that helps.

Thanks,

Craig

Also there is a command from the CUE CLI

software install downgrade

But I think this only works if you have had a previous image installed before an upgrade to 3.x but you might want to try that as well.
