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

In order to view if a firmware version is Mature or a Feature, you can use the above article to login to Fortinet support site, follow the instructions where it walks you through to the download page.

You can see "FFW_2600F-v7.2.9.M-build1688-FORTINET.out" for 7.2.9 version where M refers to mature version and "FFW_2600F-v7.4.4.F-build2662-FORTINET.out" for 7.4.4 version where "v7.4.4.F" F refers to Feature.
