Overview

This section covers moving an on-premises Business Central deployment to 2025 release wave 2 (version 27). It has four pages: an overview of upgrade paths, a page of considerations before upgrading, a procedure for installing a version 27 update, and a step-by-step procedure for upgrading the Microsoft System and Base Application.

Start with the overview page on upgrade paths. It covers deprecated features and the system application refactoring. Then read the considerations page, which lists items to check before you begin. Finally, follow either the update installation page or the System and Base Application upgrade page, depending on your scenario.

The technical steps are similar in both procedures: database conversion, extension publishing, tenant synchronization, and data upgrade. The upgrade page also covers permission set migration and encryption management.
