Upgrade Windows Azure Active Directory Sync and Azure Active Directory Sync
Azure AD Connect is the best way to connect your on-premises directory with Azure AD and Office 365. This is a great time to upgrade to Azure AD Connect from Windows Azure Active Directory Sync (DirSync) or Azure AD Sync as these tools are now deprecated and are no longer supported as of April 13, 2017.
The two identity synchronization tools that are deprecated were offered for single forest customers (DirSync) and for multi-forest and other advanced customers (Azure AD Sync). These older tools have been replaced with a single solution that is available for all scenarios: Azure AD Connect. It offers new functionality, feature enhancements, and support for new scenarios. To be able to continue to synchronize your on-premises identity data to Azure AD and Office 365, we strongly recommend that you upgrade to Azure AD Connect. Microsoft does not guarantee these older versions to work after December 31, 2017.
The last release of DirSync was released in July 2014 and the last release of Azure AD Sync was released in May 2015.
What is Azure AD Connect
Azure AD Connect is the successor to DirSync and Azure AD Sync. It combines all scenarios these two supported. You can read more about it in Integrating your on-premises identities with Azure Active Directory.

How to transition to Azure AD Connect
If you are running DirSync, there are two ways you can upgrade: In-place upgrade and parallel deployment. An in-place upgrade is recommended for most customers and if you have a recent operating system and less than 50,000 objects. In other cases, it is recommended to do a parallel deployment where your DirSync configuration is moved to a new server running Azure AD Connect.

Q: I have received an email notification from the Azure Team and/or a message from the Office 365 message center, but I am using Connect.
The notification was also sent to customers using Azure AD Connect with a build number 1.0.*.0 (using a pre-1.1 release).

The automatic upgrade feature introduced in 1.1 makes it easy to always have a recent version of Azure AD Connect installed.
