Apologies I posted the content of same URL twice, here is the second one:

Introduction
This procedure is used to manually upgrade CDN Enterprise equipment from ECDN 2.X and 3.X to ACNS. The safe procedure for upgrading ECDN is by using the manual upgrade procedure as laid out in the ACNS documentation on CCO.
In some circumstances you may need to upgrade without having access to the GUI. In these cases follow this step-by-step procedure for either CDM or CE. If your Content Engine does not have a CDM available, or for some reason you received a CE5?0-CDN when you should have received a CE5?0, you will want to use this procedure.
If your CDM failed to upgrade, and the HTTP process will not allow the use of the GUI to perform the upgrade, you will want to use this procedure.
Prerequisites
Readers of this document should be familiar with the following:
Basic Unix/Linux
ECDN
ACNS
Components Used
This process has been tested with:
CE560-CDN CDN software 3.0.3rc4
CE560-CDN CDN software 3.0.2rc10
Going to:
ACNS 4.1.1
This procedure will work with the following hardware:
CE-507-CDN
CE-560-CDN
CE-590-CDN
CDM-4650
CDM-4630
This procedure will work with the following software:
2.1.X ECDN
3.X ECDN
Step-by-Step Instructions
The procedure for the upgrade is below. Each step must be followed or the upgrade will fail. Please allow 30-60 minutes to complete.
Connect your Content Engine's ethernet interface to a network.
Turn on the Content Engine, and make sure you have a console connection.
Login to the console as root. The default password is default.
Stop the Sonoma software.
/etc/rc.d/rc2.d/K95sonomafs stop
Configure the Ethernet interface.
ifconfig eth0 ip-addr netmask mask broadcast bcast
route add 0.0.0.0/0 gw gateway-address
Clean and mount the filesystems.
fsck /sonoma/dist
fsck /sonoma/state
mount /sonoma/dist
mount /sonoma/state
Copy the upgrade image to /sonoma/state/ftp/export. And verify file integrity
cd /sonoma/state/ftp/export
ftp ftpserver-address
binary
prompt
hash
get ecdn-acns.upg
bye
spdist -t ecdn-acns.upg
Type:
sync
reboot
login again using the root username and password default
Set the date.
date mmddhhmmyyyy (MonthDayHourMinuteYear)
Indicate we are doing an upgrade.
touch /tmp/manual-upgrade
Upgrade the software.
/sonoma/sys/bin/upgrade /sonoma/state/ftp/export/ecdn-acns.upg
Note: There will be some error messages if upgrading from 2.x software, but not from 3.0.x software. Your output may appear to be similar to the following:
upg-ruby-install: Start upgrade to ruby installation
Run preinstall to install wmt packagepreinstall...
and next you should see the lines:
upg-ruby-move: Total free space: 14174164, required: 7340032
upg-ruby-setupflashdevice.sh: Done setting up flash device.
Added linux
Added ruby *
Reboot the Content Engine.
Important Note: It is very important not to disturb the CE during this reboot, and allow lots of time for it to finish. This is where most of the critical upgrade process occurs.
sync
reboot
You will see the bootup which should include:
Cisco CE Booting From Flash.

LILLOO bboooott::
LLooaaddiinngg rruubbyy..................................
and then the login prompt for "Cisco Content Delivery Network..."
and more messages, followed by a "." every few seconds....
CAUTION: DO NOT DISTURB THIS PROCESS.
After about 20-minutes, this should be done.
When you are presented with a prompt:
Cisco Content Engine Console
Username:
you will know that you are finished.
Now that you have a ACNS 4.0.1 box, you will want to adjust the partition sizes by following the instructions in Configuring and Maintaining Disk Storage.
