NOTE: While downgrading to an earlier release, OS10 removes the existing 10.5.1.0 image. This process takes about 10
minutes to 20 minutes of downtime, depending on your device.
Prerequisites
Obtain a backup of the configuration data. Ensure that you have a copy of the license files. Reapply the configuration data and
licenses files after you reload the 10.5.0.0 or earlier image.
1. Back up the current running configuration to the startup configuration in EXEC mode.
OS10# copy running-configuration startup-configuration
2. Back up the startup configuration (startup.xml) in EXEC mode.
copy config://startup.xml ftp://userid:passwd@hostip/filepath/10.5.0.0-startup.xml
3. Download the OS10 binary image for Release 10.5.0.0, also called the standby image, from a local server using the image
download server-filepath/filename command in EXEC mode; for example:
OS10# image download sftp://admin:passwd@10.1.1.1/home/admin/images/OS10EE.bin
4. (Optional) View the current software download status in EXEC mode.
OS10# show image status
5. Install the OS10 standby image using the image install file-url command in EXEC mode, where filename is the
name of the image file downloaded in Step 3 with the image download command; for example:
OS10# image install image://OS10EE.bin
6. (Optional) View the status of the software installation in EXEC mode.
OS10# show image status

● During this stage, the show boot detail command displays the details of the previous image that was installed.
The boot system active | standby command is not applicable during this state.
● If you install a new image using the image install command, the current staging image is replaced with the new
image that you have installed and you cannot downgrade to the previous version.
7. Reload the new software image in EXEC mode. This command performs a fresh installation of Release 10.5.0.0. Release
10.5.0.0 is installed as both the active and standby images.
OS10# reload
8. Use the show version command in EXEC mode to verify that the downloaded OS10 image is installed as the current
running version.
OS10# show version
