# Migrate SQL Server database with Amazon DMS ongoing replication
<a name="chap-manageddatabases.sql-server-rds-sql-server-replication"></a>

After you complete the full load, set up ongoing replication using Amazon DMS to keep the source and target databases synchronized. To configure the ongoing replication task, open the Amazon DMS console. On the **Create database migration task** page, follow these three steps.
+ For **Migration type**, select **Replicate ongoing changes**.
+ Under **CDC start mode for source transactions**, select **Specify a log sequence number**.
+ Under **System change number**, enter the SQL Server log sequence number that you captured during the full load.
