2. Run the installer as Administrator.
3. Select “Upgrade” when prompted.
3. Automate the Upgrade (For Large Deployments)
Use this PowerShell script to automate upgrades across multiple servers:
$InstallerPath = "C:\Path\To\AzureADConnect.msi" Start-Process -FilePath "msiexec.exe" -ArgumentList "/i <code>"$InstallerPath</code>" /qn" -Wait
4. Post-Upgrade Validation
Ensure synchronization is functioning correctly:
