Upgrading FortiSOAR using the Offline Repository

1. Ensure that the offline repository host is accessible from the FortiSOAR appliance and ensure that your ssh session does not timeout, run the tmux command:
   [root@localhost ~]# tmux
2. If you are using your private repository to install or upgrade FortiSOAR, then use the following command to export the "custom_yum_url" variable before running the fresh install or upgrade script:
   export custom_yum_url=<"custom_yum_url_name">
   
3. Download the upgrade installer for FortiSOAR7.4.2 using the following command:
   [root@localhost ~]# wget https://<offline repo>/7.4.2/upgrade-fortisoar-7.4.2.bin
4. To upgrade to FortiSOAR7.4.2, run the following command as a root user:
   [root@localhost ~]# sh upgrade-fortisoar-7.4.2.bin
   If you have not deployed an SSL certificate on your offline repo or you have a self-signed certificate deployed on your offline repo, then run the following command on plain Rocky Linux or RHEL system, to ignore the SSL check while upgrading FortiSOAR:
   [root@localhost ~]# sh upgrade-fortisoar-7.4.2.bin --ignore-ssl-check
