Upgrading MDT (Microsoft Deployment Toolkit) is generally not an issue – the main points are:
- Upgrade the Windows ADK before upgrading MDT.
- Make sure you have a backup (or can restore to a pre-upgraded MDT) of the Deployment Share – the Upgrade will upgrade the schema of the MDT database – including allowing new ADK features for your Deployment Share.
Now that we have a backup it is now time to go through the Windows ADK (Windows Assessment and Deployment Kit) upgrade on the MDT server and MDT current branch update. Follow the guide below to complete.
Upgrade Windows ADK
I will be using Windows ADK for Windows 10, version 1607 in my example.
- Download the latest Windows ADK – https://developer.microsoft.com/en-us/windows/hardware/windows-assessment-deployment-kit and save the setup file to your MDT server.
- If you try to install the ADK without upgrading, you will get the following error:
- So open Program and Features and select Windows Assessment and Deployment Kit – Windows 10 and select Uninstall to uninstall the old ADK (in this example I am uninstalling the v1511 Windows 10 ADK).
- Select Yes to uninstall the Windows ADK and Close when the uninstall has been completed
- Now that the old Windows ADK has been uninstalled you can now launch the new Windows ADK downloaded in Step 1 and make sure Install the Windows Assessment and Deployment Kit – Windows 10 to this computer is selected and the install path is correct and click Next
- You can either select Yes or No to allow Microsoft to collect usage data – I am just going to select No and click Next to proceed with the install
Click Accept on the license agreement
You will now get greeted by a dialog for installing the features of the Windows ADK – you need: Deployment Tools, Windows Preinstallation Environment (Windows PE) and User State Migration Tool (USMT) and select Install
- Once the Windows Assessment and Deployment Kit installation has been completed, restart your MDT server (this is not required – but I prefer to do it to make sure any registered DLLs or registry changes have taken affect and it is in a clean state).
- Now that the Windows ADK has been updated – it is time to download the Microsoft Deployment Toolkit – https://www.microsoft.com/en-us/download/details.aspx?id=54259 by selecting Download
- We are upgrading the x64 version so select this and click Next (same process for x32 – just download that instead).
12. Select Run to start the install
- You will now have the Install Microsoft Deployment Toolkit Setup wizard – select Next to start the install
- Accept the License Agreement and select Next
- Make sure that Microsoft Deployment Toolkit – Documents and Tools and Templates are select and the install path is correct (matches your current MDT install) and click Next
Select Yes or No to joining the Customer Experience Improvement Program and select Next
Finally – click Install to start the MDT install
Once installed click Finish
Open the Deployment Workbench
- It should automatically have your Deployment Share listed under Deployment Shares – if you will need to click File, Add Deployment Share to add your deployment share. Right click your deployment share and select Upgrade Deployment Share
- Verify that the information is correct and click Next to start the Upgrade
- This will start the upgrade of the Deployment Share
Once the Upgrade of the Deployment Share has been completed – it is time to upgrade the Boot Image
Right click your Deployment Share again – and instead of Upgrade, there will be Update. Select Update Deployment Share
- You will be greeted by the Update Deployment Share Wizard – select completely regenerate the boot images and click Next
- You will then be forwarded to a review page, verify the permissions are correct and click Next to start regenerating the boot images.
- Once completed you are finished. You have now hopefully successfully upgraded the ADK, MDT and Boot Images.
