Summary
This pattern provides guidance for migrating from an on-premises Microsoft SQL Server database to Amazon Relational Database Service (Amazon RDS) for Microsoft SQL Server. It describes two options for migration: using AWS Data Migration Service (AWS DMS) or using native Microsoft SQL Server tools such as Copy Database Wizard.
Prerequisites and limitations
Prerequisites
-
An active AWS account
-
A source Microsoft SQL Server database in an on-premises data center
Limitations
-
Database size limit: 16 TB
Product versions
-
SQL Server 2012-2017, Enterprise, Standard, Workgroup, and Developer editions. For the latest list of supported versions and features, see Microsoft SQL Server on Amazon RDS in the AWS documentation. If you're using AWS DMS, see also Using a Microsoft SQL Server Database as a Target for AWS DMS for SQL Server versions supported by AWS DMS.
