Directly upgrade new FG to 7.2.9

[johnlloyd_13]

hi,

i'll be getting a new FG 401 but don't know yet which FortiOS code.

i usually get OS 6.4.6 with newer device.

my question is, since this is a new/blank FG, can i jump directly to 7.2.9?

or do i still follow the "lengthy" upgrade path? 6.4.6 > 6.4.8 > 6.4.10 M > 7.010 M > 7.2.5 F > 7.2.7 M > 7.2.9 M

to my knowledge you follow the upgrade path when the FG is configured/in production so that it will "update" CLI syntax/command with the newer OS.

Hello @johnlloyd_13 ,

In my opinion, you can upgrade the device directly to 7.2.9. Because this device not include any configuration. Even so, my preference is always to upload images from tftp for such situations. I feel at ease because the device is reset while switching to the new version.

As there is no existing configuration, its fine to directly upgrade to 7.2.9

You can directly Upgrade to version 7.2.9 using GUI as well.
