🔄 IVANTI EPM Agent Reinstallation via Scheduled Task

When migrating from an old IVANTI EPM agent to a new version, a direct redeployment using IVANTI itself is not always possible or reliable.

This method provides a workaround using a scheduled task, deployed via IVANTI, that installs the new agent after reboot.

🧩 How It Works

📁 Files Included

CreateTask.ps1
Creates a scheduled task that runs after reboot (with a 5-minute delay). This script is deployed via IVANTI.
InstallIvantiAgent.ps1
The script executed by the scheduled task. It:
- Downloads the new agent installer from a web share (preferably hosted on the Core Server)
- Installs the new agent
- Deletes the scheduled task once done
DeleteTask.ps1 (optional)
Can be used to manually remove the scheduled task if needed.

⚙️ Configuration

Before using the script, make sure to configure the following variables in InstallIvantiAgent.ps1:

$baseUrl = "http://epm2024.monlab.lan/share/ivanti/agent/"
$fileNames = @(
    "d3873a1c.0",
    "EPM_Manifest",
    "EPMAgentInstaller.exe",
    "EPM2024Agent.txt"
)
$hostName = "epm2024.monlab.lan"

$baseUrl must point to the web share where your IVANTI agent files are hosted (preferably on the Core Server).

$fileNames should include all required files for the agent installation.

$hostName is used for validation or connection checks and should match your Core Server’s hostname.

🚀 Deployment Steps

Use IVANTI to push CreateTask.ps1 to the target machine.
After the next reboot, InstallIvantiAgent.ps1 runs via the scheduled task.
The agent is reinstalled and the task is removed automatically.

💡 Recommendations

Host the agent installer and InstallIvantiAgent.ps1 on a web share accessible from all target machines.
Make sure the scheduled task runs with appropriate permissions.

📘 Tip

This method avoids issues caused by trying to overwrite or update the agent while it is running, ensuring a cleaner migration process.
