## Overview

This section covers moving data from on-premises systems to Business Central online. The entry page, "Migrate on-premises data to Business Central online", explains the options: full data migration from Business Central, Dynamics GP, Dynamics SL, or Dynamics NAV, or a reimplementation approach that brings over essential data only (for example with configuration packages).

Each source has its own subtopic. The Business Central, GP, and SL subtopics follow a similar flow: overview, preparation, cloud migration setup, data replication, data upgrade, and completion. GP and SL also cover post-migration users and permissions. The NAV subtopic describes the path through BC14, the BC14 reimplementation option, and converting C/AL customizations to AL extensions.

Supporting pages include custom migration from any SQL source (no-code mappings, custom migration apps, or extending the BC14 reimplementation tool), an FAQ on requirements and limits, and a troubleshooting guide. Start with the overview page, then go to the subtopic for your source system.

## Key points

- Supported sources: Business Central, Dynamics GP, Dynamics SL, and Dynamics NAV on-premises, plus custom SQL-based sources.
- A reimplementation approach is an alternative that migrates only essential data, using options such as configuration packages.
- Dynamics NAV migration follows a path through BC14, with a BC14 reimplementation option and guidance on converting C/AL customizations to AL extensions.
- Custom migrations can use no-code table, replication, and setup mappings, custom migration apps (provider and table mapping interfaces), or an extended BC14 reimplementation tool.
- The FAQ covers system requirements, data limits, SQL connection strings, the self-hosted integration runtime, Azure Data Factory, the intelligent cloud permission set, extension data migration, and data compression.
- The troubleshooting guide covers SQL Server compatibility, change tracking, migration user permissions, Integration Runtime setup, company name validation, and the tenant media table, and refers to versions 23, 24, and 25.
- BC, GP, and SL migrations each go through preparation, setup, data replication, data upgrade, and completion phases.
