In this chapter, we looked at the best practices of moving an existing monolithic C/AL solution to the new extension architecture and to the AL language. We also saw the best practices of architecting your solution, such as how to convert existing C/AL code into AL in a semi-automatic way, and how to handle common problems during the migration phase of your existing solution.

Toward the end of this chapter, you learned how to migrate to the new Dynamics 365 Business Central platform and the best practices to adopt when starting a project for a new solution. Now, you have a clear vision of the tools to use to migrate existing code to AL and the steps that are required to start this migration activity.

In the next chapter, we'll learn how third-party tools can help us work with AL and extensions, and also help us move our existing solutions to the new Dynamics 365 Business Central architecture.
