Firmware Upgrade Paths
|
When upgrading from 7.4.x or 7.2.11 to 7.4.5, upgrade the FAZBD OS first. Upgrading the bootloader before the OS can result in a bootloader upgrade failure. |
The following table identifies the supported FortiAnalyzer-BigData upgrade paths and whether the upgrade requires a rebuild of the log database.
| Initial Version | Upgrade to | Log Database Rebuild |
|---|---|---|

No |
| 6.4.5 or later | Latest 6.4 version, then to latest 7.0 version | No |

FortiGate units with logdisk buffer log data while FortiAnalyzer units are rebooting. In most cases, the buffer is enough to cover the time needed for FortiAnalyzer to reboot. However, Fortinet still recommends configuring multiple log destinations to ensure no logs are lost. |
Fortinet Security Fabric
If you are upgrading the firmware for a FortiAnalyzer-BigData unit that is part of a FortiOS Security Fabric, be aware of how the FortiOS Security Fabric upgrade affects the FortiAnalyzer-BigData upgrade. You must upgrade the products in the Security Fabric in a specific order. For example, you must upgrade FortiAnalyzer-BigData to 7.2.0 or later before you upgrade FortiOS to 7.2.0 or later.
Upgrade bootloader
If you are currently using FortiAnalyzer-BigData, we recommend upgrading bootloader.
To upgrade bootloader, connect to the Security Event Manager Controller and run the following command:
fazbdctl upgrade bootloader
You can also upgrade bootloader from the GUI. For more information, see Bootloader in the FortiAnalyzer-BigData Administration Guide.
