Directory Sync Pro for Active Directory 20.11.4 - Installation Guide

This document details the following:

• Requirements for implementing Directory Sync Pro and Migrator Pro. These include the requirements for each of the servers needed to run Directory Sync Pro, as well as any environmental requirements.
• Information on how to install Directory Sync Pro and Migrator Pro.

This document assumes the reader has Active Directory and Exchange administration skills. If Active Directory or Exchange Administration topics mentioned in this document are not understood, please reference the product(s) System Administration documentation.

• All AD Functional Levels supported by Microsoft for a Microsoft Windows Server operating system listed below are supported for migration from/to Domain controllers running on that same Operating System. For example, Windows Server 2016 functional levels are supported on Windows Server 2022, Windows Server 2019, and Windows Server 2016. For full details see Microsoft’s documentation of Active Directory Domain Services Functional Levels in Windows Server on Microsoft Learn.

  NOTE: Windows Server 2003 functional levels are supported only on Windows Server 2016, Windows Server 2012 R2, and Windows Server 2012. That is, Microsoft does not support Windows Server 2003 functional levels on Windows Server 2019 or Windows Server 2022. Microsoft ends extended support for Windows Server 2012 on October 10, 2023. Customers should have moved their Domain Controllers off of Windows Server 2012 and Windows Server 2012 R2 by now.

• Directory Sync Pro and Migrator Pro supports connections with TLS 1.2 and higher to Active Directory Domain Controllers. However, the Directory Sync Service, Active Directory Service, and Password Propagation Service requires TLS 1.2 to be enabled due to Microsoft SQL Server requirements.
