Overview

This section is for administrators of on-premises Business Central who are moving to 2026 release wave 1 (version 28). It has four pages: an upgrade overview, a pre-upgrade considerations page, a step-by-step upgrade guide, and an update installation guide.

Start with the overview page, which explains the required upgrade paths, intermediate versions and the review of deprecated features. Then read the considerations page, which covers deprecated or redesigned functionality, schema changes, extension performance impact and deployment changes. After that, follow the upgrade page for unmodified applications from versions 25, 26 or 27. Use the install update page for platform-only or application updates within version 28.

Key points

• The upgrade page covers unmodified applications moving from version 25, 26 or 27 to version 28.
• Upgrade steps include application database conversion, extension publishing and installation, tenant synchronization, and data upgrade execution.
• The upgrade page also covers permission sets migration and encryption key management.
• The overview page says earlier versions may need specific upgrade paths with intermediate versions, and deprecated features should be reviewed first.
