Guidelines and Limitations for Readiness Checks
These guidelines and limitations apply to Firepower readiness checks.
Evaluates Firepower Software Readiness Only
The readiness check is for Firepower software readiness only. It does not assess preparedness for intrusion rule, VDB, or GeoDB updates.
Requires Version 6.1+
The readiness check was introduced in Version 6.1. If you are:
Upgrading to Version 6.1: Install the Version 6.1 preinstallation package before you run the readiness check.
Upgrading to any later version, including Version 6.1 patches: Readiness check is built in.
FMC and Standalone Devices Only
You can use the Firepower Management Center to perform the readiness check on itself and its standalone managed devices only.
For clustered devices, stacked devices, and devices in high availability pairs, you can run the readiness check from the Linux shell (also called expert mode). To run the check, you must first push or copy the upgrade package to the correct location on each device, then use this command:
The time required to run the readiness check varies depending on appliance model and database size. You may find it expedient to forgo readiness checks if your deployment is large.
You can reduce the amount of time it takes to run device readiness checks by pushing upgrade packages to devices before you begin. Requires an FMC running Version 6.2.3+.
During The Check/Failed Checks
Do not manually reboot, or shut down an appliance running readiness checks. If your appliance fails the readiness check, correct the issues and run the readiness check again. If the readiness check exposes issues that you cannot resolve, do not begin the upgrade. Instead, contact Cisco TAC.
