Make sure that your systems meet all requirements.
Follow these procedures to benefit from the new features and enhancements of this version.
Not all manual customization of the appliance configuration is preserved when upgrading. If the TIE server properties or database configuration were modified, create a backup and apply changes after the upgrade.
Make sure the following URLs are whitelisted in your enterprise firewall for the TIE server to access Trellix GTI (if enabled):
tieserver.rest.gti.trellix.com
tie.repl.gti.trellix.com
To minimize network disruption, schedule maintenance downtime for the upgrade and run a vacuum analyze task for database maintenance. For more information see KB86092.
Important
The upgrade process to TIE server 4.x.x forces a full database replication from the Primary Server to every Secondary and Reporting Secondary Server of the topology. Expect high network usage during the Secondary servers upgrade. Database upgrade can take several minutes depending on database size and bandwidth conditions.
Create a snapshot of your virtual machine (Primary instance, if applicable) on the VMware vSphere client. For instructions, see the VMware vSphere documentation. If you are using a non-virtual environment, see KB86092 for instructions to create bare-metal backups.
Make sure that you have full connectivity in the DXL fabrics. All your brokers must be listed in green.
