Hi everyone,
We have a standalone Cisco VCS CE1000 Appliance,it's software is X8.6.1,we need downgrade to X7.2.3. I know we need a release key for downgrade, but there is a error always occur.
Just like this:
log “root:Release key invalid!”
System Upgrade:System error:Relase key invalid !
I want to know how to downgrade the VCS from X8.6.1 to X7.2.3. Is there any detail steps?
Thanks

I think CE is first launched with x8.1 release.
You can rename the software file "tandberg-image.tar.gz" and release key in a text file and name as "release-key" (without the extension .txt). Login via root and then upload the release key first and then the software file under /tmp folder. Wait on root prompt. If the downgrade work you will see notification on root CLI.
However as i said, i am not 100% sure if its going to work or not. Give it a try and update me as well :).

Important that CE1000 Appliance support X8.1.1 and onward.
This mean you CAN'T downgrade CE1000 Appliance to X7.x software version.

It should be pretty much the same process as upgrading, but you just use a different (older) release key and firmware file.
Go to Maintenance / Upgrade.
Click the "Choose file" button and select the X7.2.3 firmware .tar.gz file
Put the X7.2.3 Release Key in to the "Release Key" field.
Click the Upgrade button.

Wayne has the correct procedure, however I believe the VCS will factory reset during the downgrade, so make sure you take screenshots of every page as you will need to manually rebuild all the settings.
This quote is from the VCS Release notes:
"We do not support downgrades. Do not install a previous Cisco VCS version onto a system that is running a newer version. If you do so, the system configuration will not be preserved."

What is the reason, you are trying to downgrade? As far as i remember for CE1000 you needed x8.1.1. or later.
Have you tried the other workaround process by uploading the file to /tmp folder from root? Not sure if it will work, but worth a try.

HI Alok Thanks for you response. It's really for what you say? but i didn't notice the CE1000 need X8.1.1 or later. Is there any document for explain this ?
And how to do "uploading the file to /tmp folder from root" ?

Yes, isn't your question is regarding CE1000? Or a difference CE flavour? Because the new CE for e.g. 1200 version's are configured to work only as Expressway series and not VCS. Which is why you can't downgrade it beyond x8.x version as the Expressway capability didn't used to exists at x7.x version.
