Summary

Argent AT has built-in automatic upgrading mechanism for all Engines

When customer upgrades the Main Engine, all Remote Engines should download the latest required files, and complete upgrade automatically

However, there is still a common question ‘I Am Updating 50 Trusted Agents, How Do I See All On A Single Screen?’

This can be easily accomplished by using Global System View

The column ‘Version’ lists the exact version of the Remote Engine

When automatic upgrade has completed, all Engines should run on the same version

Technical Background

A Remote Engine periodically contacts Main Engine and exchange version information through TCP/IP connection

When the Remote Engine detects the version difference, it starts automatic upgrade

• It first queries for all required files
• Then it downloads them into local cache $UPGRADE

  If the downloading is disrupted somehow, the Engine will resume from what was left without downloading the files that has been downloaded successfully

• When all required files are downloaded successfully, the Engine starts an external upgrade process and shutdown the service
• The upgrade process updates all the files and registries, then restart the Engine service

A Remote Engine is upgraded only if the Engine is running

So if a Remote Engine is not automatically upgraded to the same version as Main Engine, check if the Engine service is running
