Hello, the previous administrator did the update in the wrong order, jumped a few steps of the update path. That's why I have now problems with a few functionalities. For example, I can not set logs to memory, because in Display Logs From, I have the message "Selected log location is currently disabled". In console I see that I have "log momory enable". Current firmware version FortiOS v5.6.6 build1630 (GA). As I know the base version from which the updates were started is 5.4.1. How to fix it? Is it possible to go back to 5.4.1 and update the device correctly?
If it was directly upgraded to 5.6.6, the config thrown out during the upgrade is in "diag debug config-error-log read".
I'm not sure if that's the cause of that particular issue though. After 5.6, they're more forcing to use remote logging either FortiAnalyzer or FortiCloud, and discouraging memory log. But 60E doesn't have local storage/SSD.
Assuming you are on site with direct access to the fgt and have a backup copy of the config file before the upgrade(s), you certain can downgrade the firmware, then restore the backup config.
Those 60Es do not have internal disk storage, but do not understand why logging to memory isn't working (unless it is something on 5.6.x. I would check "config log memory filter" and "log gui-display".
I'm afraid I do not have previous configurations. The last one I have is # config-version = FGT60E-5.6.3-FW-build1547-171204. Yes I'm on site with direct access to the fgt. From version 5.6.3 I have been updating the device.
