TZ300 Firmware Upgrade

My TZ300 Firmware is at SonicOS Enh I want to update the firmware to latest version. Since there are many firmware levels to go through before I reach v6.5, I was wondering if I need to install firmware updates in sequence or can I just install the latest firmware ?

    Hi @SteveGuh . Looks like your TZ300 has never been upgraded since the purchase and deployment. Technically speaking you don't need to do incremental updates. Please keep in mind that your firmware 6.2.3.x has CFS 3.0 and starting with 6.2.6.x we have CFS 4.0 on Gen6 firewalls which is different in functionality, and for this reason you have to reconfigure CFS after the firmware update. For more details please refer to the following KB article.
