In this article by Marcelo Leal, author of Implementing Samba 4, the reader will learn some of the biggest differences between the Samba software Versions 3 and 4, and based on that, will understand the impact and the relevant considerations before planning a successful upgrade. The main aspects of such differences will be focused on the different working models and the new features and benefits that the upgrade can leverage.
We will learn about a step-by-step procedure to execute the upgrade and all the commands and scripts needed to go from Samba 3 to Samba 4's fully functional Domain Controller network services.
We will describe a guideline that can be well suited and requires just a few changes for small and medium installations, but bigger and more complex environments will need adjustments and customizations. The variety of configurations in production of the Samba Server Version 3 use cases are huge, and we will not be able to handle all the variations that our readers have implemented in their respective environments, but all the procedures and use case examples presented here should work as a rich base.Read Upgrading from Samba Server Version 3 in full
