## Overview

This section explains how to move from an on-premises system to Business Central online. It starts with the choice of approach: a full data migration, a custom migration, or a reimplementation that brings over only essential data, for example with configuration packages. Source systems named are Business Central, Dynamics GP, Dynamics SL and Dynamics NAV.

The overview page describes the end-to-end process in five phases, from preparation through completion and go-live. It also covers the components involved: cloud migration setup, data replication, data upgrade, Azure Data Factory pipelines, the self-hosted integration runtime and the intelligent cloud permission set. The "Managing cloud migration" page then covers day-to-day work on the Cloud Migration Management page.

Start with the on-premises migration page to pick an approach, then read the overview for the process. Use the FAQ for requirements, data limits, SQL connection strings and permissions. If you come from Dynamics GP, the GP page covers how data such as fiscal periods, chart of accounts and inventory is carried over.
