How To Upgrade AADConnect Agent From Old Version To New Version InPlace Upgrade

AADConnect Server plays important role in the Office 365 Hybrid setup. Hence that AADConnect upgrade should be taken care very seriously if it is also being used for Password Sync.

AADConnect Server plays an important role in the Office 365 Hybrid setup. Hence, this AADConnect upgrade should be carefully implemented if it is used for Password Sync.

AADConnect has three different types of upgrade options,

  1. In-Place Upgrade
    In-Place upgrade means upgrading the server which is already installed and running it currently in the production. It needs more attention to upgrade than the current server. If anything goes wrong or misbehaves while upgrading, it may cause serious issues, hence check all the steps, as I am going to explain, before proceeding with the upgrade.

  2. Automatic upgrade
    The auto-upgrade option is not recommended for the larger object's syncing as it can cause downtime or mislead the settings if anything goes wrong. It is recommended to express the installed version and not enable it with more conditions or filters.

  3. Swing migration
    The swing upgrade is highly supported where AADConnet is installed with the two servers with high availability.

In this article, we will see how to do an in-place upgrade.

Before proceeding with the upgrade,

1. Ensure the current cycle is completed as it requires full sync once AAD connect is completed.
2. Export the settings if there are any customized filters applied.
