Azure ad connect requirements

Before going for the installation of Azure ad connect, You need to consider the below points as prerequisites.

Azure AD

You should have an Azure AD tenant. You can get one by creating a free Azure account. If you don’t have an account till now, you can follow my article How to Create Azure Free Account (Step by Step tutorial) to create an Azure free account.

Active Directory

You can use Microsoft 365 IdFix tool to identify errors such as duplicates and formatting problems in your directory before you are going to synchronize to Azure Active Directory and Office 365.

The Active Directory schema version must be Windows Server 2003 or later version and The domain controller used by Azure Active Directory must be writable.

It is recommended to enable the Azure Active Directory recycle bin before proceeding further. This will help you to keep the accidentally deleted Azure AD user object in a soft-deleted state for 30 days. You can restore it based on your need.

If you want to install Azure AD Connect on a Domain Controller then it is not recommended due to security practices that can create problems during Azure AD Connect installation.

Operating system Requirements

Azure AD Connect must be installed on Windows Server 2012 or later version (Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019), or else you will get a warning message and it will not allow you to do the installation.

If you want to deploy Active Directory Federation Services then in that case you need TLS/SSL Certificates and you need to configure name resolution.

It is recommended to harden your Azure AD Connect server, this will reduce the security attack.

If you want to integrate an Azure AD Global Administrator account for the Azure AD tenant. This account must be a school or organization account.

PowerShell and .NET Framework

You need to install Microsoft PowerShell and .NET Framework 4.5.1 version or a later version installed on your server as Azure AD Connect depends on those.

Enable TLS 1.2

Ensure that TLS 1.2 is enabled which is needed for Azure AD Connect and do not forget to install .NET 4.5.1 hotfix.

Hardware requirements for Azure AD Connect

When the no of objects in the Active directory is less than 10,000 then the CPU required is 1.6 GHz, Memory required is 4 GB with a hard disk size of 70 GB.

In case, the no of objects in the Active directory is between 10,000 to 50,000 then the CPU required is 1.6 GHz, Memory required is 4 GB with a hard disk size of 70 GB.

If the no of objects in the Active directory is between 150,000–100,000 then the CPU required is 1.6 GHz, Memory required is 16 GB with a hard disk size of 100 GB.

But, when the no of objects in the Active directory is between 100,000–300,000 then the CPU required is 1.6 GHz, Memory required is 32 GB with a hard disk size of 300 GB.

While the no of objects in the Active directory is between 300,000–600,000 the CPU required is 1.6 GHz, Memory required is 32 GB with a hard disk size of 450 GB.

Azure ad connect upgrade

Here, we will discuss the methods to upgrade the current version of Azure ad connect to the latest version. It is always suggested to keep the updated version.

Update Azure AD connect

There are three ways to upgrade the Azure ad connect version

Automatic upgrade
In-place upgrade
Swing migration

Automatic upgrade

It is always a better option to enable the Automatic upgrade option which will always upgrade to the current version automatically. It is enabled by default for express installations and DirSync upgrades.

The current status of the Automatic upgrade can be checked by the below PowerShell cmdlet

PS C:\windows\system32> Get-ADSyncAutoUpgrade

Azure ad connect upgrade — download aad connect

It has four states i.e Enabled (Automatic upgrade feature is already enabled), Suspended (The system is not eligible to enable Automatic upgrade), and Disabled (Automatic upgrade feature is disabled on the system).

With the help of the Set-ADSyncAutoUpgrade PowerShell command, you can change the status between Enabled and Disabled.

In-place upgrade

This method you can use when you have a single server so that you can upgrade the installation in place on the same server. It works for moving from Azure AD Sync or Azure AD Connect.

It is a choice when you have only a single server and contains less than about 100,000 objects.

This process ensures that the new configuration is applied to all existing objects and the process might take a few hours, which depends on the number of objects.

So it is suggested to perform the in-place upgrade during a weekend.

It will check if there are no changes to the OOB configuration with the new Azure AD Connect release, then it will start a normal import/sync. But if you have made any changes to the OOB sync rules in the out-of-box, then these rules are set back to the default configuration after the upgrade process.

Swing migration

You can choose the swing migration when there are many objects in the system or you have a complex deployment.

We can also use swing migration when you are planning to make substantial changes to your configuration and we want to test them before we are going to publish them to the cloud.

For this method, there is a need for two servers

Active serve
Staging server

Active production load will be there on the Active server and the new release or configuration will be stored on the staging server. When it’s fully ready, this server is converted to the active and previous active server, where the old version or configuration installed, is converted to the staging server and is upgraded.

Ensure that both your active server and staging server are using the same version If you use Azure AD Connect on both servers and planning make only a configuration change. In case if you’re upgrading from Azure AD Sync, then these servers have different versions.

This is how to update azure ad connect whenever you required it.
