We are trying to update the ROMMON on an ASA5506 using CLI. The install keeps updating but the full installation fails at the last step.

Problem: Customer is facing issues when upgrading the ASA5506 using CLI from the 1.1.8 version to 1.1.14 version.

Resolution:

Before upgrading the Secure Firewall ASA, you should perform the following preparation:

• Check compatibility between different versions of operating systems; for example, make sure that the ASA version is compatible with the ASA FirePOWER module version.

• Check the upgrade path for the current version to the target version; ensure you plan for any intermediate versions required for each operating system.

• Check for guidelines and limitations that affect your intermediate and target versions, or that affect failover and clustering zero downtime upgrading.

• Download all software packages required from Cisco.com.

• Back up your configurations, especially if there is a configuration migration.

After the recommendations:

1) I called the customer to recommend a zoom meeting to explain these details and the regular path for ASA5506  from older versions to the newest one.
