I want to downgrade the image in partition 0 of an A620 controller from 6.1.1 to 5.0.4 - the controller is booting from partition 1 (AOS 6.1.2). The downgrade of partition 0 fails with an error stating that there is "Not enough free space (need 55 MB)". I am not sure how to delete the image in partition 0.
What I am ultimately trying to do is upgrade some RAP5s from 3.1 to 5.0, so that I can connect them to my production controller, which is running 6.1.3. I was hoping to downgrade this spare controller, connect the RAP5s to it, so that I could upgrade them, and then connect them to my production controller.

On the CLI use "show storage command" and verify that you have least 75 MB of /flash available.
If not, you must delete files from the file system before attempting a local
file upgrade. Run the dir command to list all files (or use WebUI > Maintenance > Files). Delete all unnecessary
files including crash files and logs.tar file. To ensure that all temporary (crash) files are removed, perform a tar
crash and then remove the crash.tar file from the controller. You can copy these files on your local computer for future purposes.

Thank you, Sathya. I can see from the output below that I only have 54MB of storage available in the /flash directory (file system /dev/mtdbblock1). I assume from your response that this is where the uploaded image gets placed during the upgrade process. I am not sure how to change to or list what is in the /flash directory, so that I know what I can know what to delete from here.
Filesystem Size Used Available Use% Mounted on
/dev/mtdblock11 156.0M 102.0M 54.0M 65% /flash
none 300.0M 41.7M 258.3M 14% /tmp
/dev/mtdblock9 50.0M 24.3M 25.7M 49% /mnt/img0
/dev/mtdblock10 50.0M 24.3M 25.7M 49% /mnt/img1
I also assume that the /mnt/img0 and img1 directories are partition 0 and partition 1?
