Fortigate offline packages updates

[myasin]

Hi

We have fortigate firewalls to be installed and managed by Fortimanager, they will have internet access, so the licenses and packages updates will be done offline, I have two questions on this regard;

- What is the schedule of packages updates in fortinet portal, like every quarter, and how to know about new updates?

- Is there specific configuration for fortigate to get updates from fortimanager (rather than the Central-Management settings)?

"As the below document page-8 states about some other steps, but I dont know if they are required"
