Overview

This section covers the replication step of migrating from Dynamics SL to Business Central online. It has two pages: one explains the concepts and one explains the hands-on tasks.

“Data replication overview” describes how data moves from the on-premises database to the online environment. It covers the large table and small table flows, Azure BLOB storage, Azure Data Factory, the integration runtime, company initialization, and how rerunning replication uses change tracking.

“Run and manage data replication” is the practical page. It uses the Cloud Migration Management page to create a diagnostics run, start replication, monitor progress, and review the Migration Log when errors occur. Start with the overview to understand the flow, then use the run page for the actual migration.
