Fortigate 100D Best & Latest stable firmware

Hi,

in general, patch updates within the same main line (in your case, v6.2) are recommended and seldomly dangerous. Changing into a different main line (v6.4 or v7.0) needs deeper inspection of "What's new" and Release Note documents, some research on the Forums etc.

Best practice says "do not jump onto the zero patch" or even patches 0-4. So, for v6.2 you can update to v6.2.10 without hesitation. If available, I would even try to upgrade to v6.4.8 which is stable, as this new main line offers a lot of improvements.

But, IMHO, putting v7.0 onto a production FGT is asking for trouble at the moment. It might work well, but chances for malfunctions are higher in v7 than in v6.2 or v6.4.

Latest 6.2 is stable.

Hello,

Hope you are doing good. Please be informed every version has it own solved and known issues please check the release notes concerned with the version and you can go with the version which is suitable for your setup environment. For your information the last firmware version 100D can support is 6.2.15.

Let me know if you have any queries.

Thanks, 

Pavan

Hi @Iven_Conjamalay,

It is very hard to tell which version is more stable than which one. However, you can check the resolved issue on each one. Please refer to the "release note" section for more information "https://docs.fortinet.com/product/fortigate/6.2"
