Upgrading AsyncOS

You can download and install in a single operation, or download in the background and install later.

Note

When downloading and upgrading AsyncOS in a single operation from a local server instead of from a Cisco server, the upgrade installs immediately while downloading . A banner displays for 10 seconds at the beginning of the upgrade process. While this banner is displayed, you have the option to type Control-C to exit the upgrade process before downloading starts.

Before you begin

Choose whether you will download upgrades directly from Cisco or will host upgrade images from a server on your network. Then set up your network to support the method you choose. Then configure the appliance to obtain upgrades from your chosen source. See Choosing an Upgrade Method: Remote vs. Streaming and Configuring Upgrade and Service Update Settings.
Before installing the upgrade, follow the instructions in Before You Upgrade: Important Steps.

Procedure

Step 1

[New Web Interface Only] On the Security Management appliance, click to load the legacy web interface.

Step 2

Choose Management Appliance > System Administration > System Upgrade.

Click Upgrade Options.

Step 4

Choose an option:


To	Do This
Download and install the upgrade in a single operation	Click Download and Install. If you have already downloaded an installer, you will be prompted to overwrite the existing download.
Download an upgrade installer	Click Download only. If you have already downloaded an installer, you will be prompted to overwrite the existing download. The installer downloads in the background without interrupting service.

Step 5

Unless you are installing a previously-downloaded installer, select an AsyncOS version from the list of available upgrades.

Step 6

If you are installing:

Choose whether or not to save the current configuration to the configuration directory on the appliance.
Choose whether or not to mask the passphrases in the configuration file.

Note
You cannot load a configuration file with masked passphrases using the Configuration File page in the GUI or the loadconfig command in the CLI.
If you want to email copies of the configuration file, enter the email addresses to which you want to email the file. Use commas to separate multiple email addresses.

Step 7

Click Proceed.

Step 8

If you are installing:

Be prepared to respond to prompts during the process.

The process pauses until you respond.

A progress bar appears near the top of the page.
At the prompt, click Reboot Now.

Note
Do not interrupt power to the appliance for any reason (even to troubleshoot an upgrade issue) until at least 20 minutes have passed since you rebooted.
After about 10 minutes, access the appliance again and log in.

What to do next

If the process was interrupted, you must start the process again.
If you downloaded but did not install the upgrade:

When you are ready to install the upgrade, follow these instructions from the beginning, including the prerequisites in the Before You Begin section, but choose the Install option.
If you installed the upgrade, see After Upgrading.
