+# 🔄 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`:
+
+```powershell
+$baseUrl = "http://epm2024.monlab.lan/share/ivanti/agent/"
+$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
+
+1. Use IVANTI to push `CreateTask.ps1` to the target machine.
+2. After the next reboot, `InstallIvantiAgent.ps1` runs via the scheduled task.
+3. 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.
