Preparing to Upgrade AsyncOS
As a best practice, Cisco recommends preparing for an upgrade by taking the following steps.
Procedure
Step 1
Save the XML config file off-box.
Step 2
If you are using the Safelist/Blocklist feature, export the list off-box.
Step 3
Suspend all listeners. If you perform the upgrade from the CLI, use the
suspendlistener
command. If
you perform the upgrade from the GUI, listener suspension occurs automatically.
[The system setup wizard is run.]
