My cleints have attempted to down grade a 5200 unit to verion 09.21.11.004 from the supplied version of 10.11.03.0004 ( this is so it matches the current operational box )

The downgrade has failed with the following prompt:
Error! Upgrade is not supported from major release :10

I would like to know how can I can downgrade the unit to the required software level

I'd do the following...

- put a flash in the current controller
- upgrade to 9.21.18 and select backup image to flash
- remove the flash and put it into the new one
- don't connect the new one to the network yet
- upgrade to the flash image
- upgrade to 9.12.18
- change the parameters
- connect to the network

You will have to get a rescue image for 9.21 and either FTP it to the controller or put the uncompressed image on a flash drive and attach it to the controller. Once you have the rescue image on the controller you can then click "Upgrade Now" which will use the 9.21 rescue image to back rev to 9.21.05 (which is the version supplied in the KCS article I will provide at the end of this). At that point you should upgrade to 9.21.18.

Rod, I uploaded that file to a different link and you should have received an email.

What Ron mentions below is also a good method!
