FortiManager/FortiGate version conflicts

[zane_donaldson]

All,

we recently recieved new Fortigate appliances with FortiOS 6.0 installed.  We were not able to add them into the FortiManager because they are newer than the FortiManager itself.

If I upgrade the FortiManager, will I lose connection to my existing appliances that are running older versions of FortiOS?  

FortiManager Version: v5.6.6-build1750 181002 (GA) 

All of my current appliances: FortiGate 5.6.6,build1630 (GA)

so what is the upgrade path to 6.0 when using FortiManager?

Hi there, 

Same questions I have before we upgrade to Fortimanager 6.0.1. 

- We did not lose connections to our devices ( actually no downtime) when we did the upgrade from 5.6.0 t0  6.0.1. our fortigates are 5.6.0, 5.6.2, 5.6.5 and 5.6.6 actually. 

- You can upgrade your present 5.6.6 to 6.0.1 directly, as stated from the Release notes. 

Cheers and have a beer  :)

Hi Donalds ; 

Here is a link to the Fortimanager upgrade recommendations path : 

https://docs.fortinet.com/document/fortimanager/6.0.0/upgrade-guide/321010/introduction

it is a good aproche to dedicate an ADOM for your existing Fortigate appliaces ( 5.6.6 ) and create a New ADOM for the New Fortigate appliances ( 6.0 ) .
