i have a few Fortigate firewall running on 7.2.xx version.
Planning to upgrade to 7.4.8.
do i need to upgrade all at the same time or i can just upgrade the main FGT at our data centre and the rest at our site office at a later date ?
all are connected using ipsec tunnels
Hi @yeowkm99 ,
There is no compatibility issue between different versions of FortiGate with the IPsec. So, we can either upgrade them at same time or different time.
But please be aware of the compatibility of other devices such as FortiManager, FortiSwitch, FortiAnalyzer and so on.
Regards,
George
