Overview

This section collects supporting articles for upgrading Business Central on-premises. They cover two tasks: turning customized C/AL code into AL, and moving tables and fields from one extension to another.

The code conversion page explains how to convert customized version 14 C/AL solutions to AL with the Txt2Al conversion tool, as part of upgrading to later versions. It covers object export, AL project setup, .NET interoperability, assembly declarations and test library conversion. It also references versions 18, 19 and 20.

The subtopic on migrating tables and fields describes using migration.json to move table ownership between extensions, in both directions along the dependency graph, including ordering and constraints. It also covers the India Data Migration Toolkit for upgrading from Dynamics NAV 2016 India. Start with the code conversion page if you still have C/AL code, and use the migration subtopic when restructuring extensions.
