- Before upgrading FortiSIEM, you MUST read the changes in FortiSIEM licensing documented in the 'Licensing Guide' here.
- Customers using releases prior to 4.10.0 must first upgrade to 4.10.0 before upgrading to 5.3.1. Customers in 4.10.0 can directly upgrade to 5.3.1.
Starting with version 4.5, Supervisor requires 24 GB RAM. This is because Supervisor node is caching device monitoring status for faster performance.
If Elasticsearch is chosen as the Event Database, the Supervisor needs an additional 8 GB RAM - in this case, the minimum requirement of the Supervisor is 32 GB RAM.
If you enabled SNMP on FortiSIEM nodes (Collectors, Workers, Supervisors), it recommended that you modify the snmpd.local.conf file to store special configurations. You should not modify snmpd.conf file since FortiSIEM upgrade will wipe away the changes in snmpd.conf. To prevent changes from being lost, copy the changes to snmpd.local.conf file and then upgrade.
