How to upgrade Azure AD Connect

There are 2 methods of upgrading Azure AD Connect I want you to be interested in.

Auto Upgrade – This feature, when turned on, will automatically upgrade Azure AD Connect to the latest version after running an eligibility check on your system. I highly recommend this feature is turned OFF. You can check the status of this feature with the following command.


If you find that AD Sync Auto Upgrade is enabled in your environment, you can turn it off with the following command.

Set-ADSyncAutoUpgrade -AutoUpgradeState Disabled

In-place Upgrade – This is the preferred upgrade procedure as it simply involves downloading the latest version and running the install over the top of the previous version manually. This means you can do all the due diligence prior to the upgrade yourself.

Once you have downloaded the latest version, simply run the downloaded file and you will be presented with the following screen.

Simply click upgrade and sign in with your Azure AD credentials. Then on the last page click configure and it will handle everything else for you. Once you have completed the upgrade and full synchronisation will be run immediately after. If you wish to defer the full sync after the upgrade you can uncheck the box on the final screen which states Start the synchronisation process when the configuration completes.
