firmware upgrade

[BlueP]

Our firewall (FortiGate-500E v7.0.14, build0601) is currently experiencing issues with upgrading to newer firmware versions. There are two options available: versions 7.2.7 and 7.2.8. However, the release notes for version 7.2.7 indicate a bug affecting IPsec tunnels, while version 7.2.8 has a known issue with routing and SD-WAN

How should I determine the most suitable version for the upgrade?

known issues: 7.2.7 -->> https://docs.fortinet.com/document/fortigate/7.2.7/fortios-release-notes/236526/known-issues

known issues: 7.2.8 --> https://docs.fortinet.com/document/fortigate/7.2.8/fortios-release-notes/236526/known-issues

Agreed. IPMI/iDrac/iLo present with vulnerabilities like any software. For those concerned about firmware updates breaking servers, or otherwise causing undesirable behavior, I suggest you ensure you have a test machine in the lab.

When upgrading from version 7.0.14 to later versions, be sure not to skip version 7.0.15. Although the upgrade path tool may not indicate 7.0.15 as a required step, you should consult this article for further guidance: Technical Tip - Boot failure after upgrading to v7.0.15.

Therefore, please ensure you upgrade to 7.0.15 before proceeding to subsequent versions.

Additionally, it’s recommended to test upgrades in your lab environment first, as this issue may not occur on all devices. It can vary depending on the specific topology and device type in use.

@Umer221If my interpretation of the KB is correct, the version you shouldn't skip is not 7.0.15 but it's 7.0.14. Am I reading it wrong?

• The error message 'failed verification on /data/datafs.tar.gz' can occur when upgrading from any version lower than v7.0.14 once skipped the upgrade path and upgraded directly to v7.0.15 or above.
• Before upgrading, the system must be on the base of v7.0.14.

Thank you for catching this. Correct it is 7.0.14 version not suppose to be skipped, so it does not apply in this case.

We've learned this in a hard way and had to reload 7.0.14 from TFTP server for multiple devices. I wished we knew this much earlier. Thank you for the link, @Umer221
