Applications are closely dependent on the databases and application evolution is frequently connected with an upgrade of the application database. Database migration is process of moving customer’s database from a source instance to a destination instance. This process includes not only the move from one instance to another, but also a modernization process - from one version of SQL Server to a newer one (or from a legacy & unsupported to a supported one).
There are multiple ways to migrate databases hosted in Amazon Relational Database Service (Amazon RDS) for SQL Server to Azure SQL Managed Instance. For use cases such as migrating from Amazon Elastic Compute Cloud (Amazon EC2) to SQL Server on Azure SQL Managed Instance, you can use a number of ways and tools, including Database Migration Assistant (DMA) Link feature for SQL Managed Instance or Log Replay Service. When it comes to migrating RDS for SQL databases, we cannot use DMA or Log Replay Service methods because RDS SQL Server takes backups without checksum enabled and both of these methods require backups to have the checksum enabled in order to verify the consistency at the restore time.
This is the Multi blog post series on the Amazon RDS for SQL Server to Azure SQL Managed Instance migration that will serve as an introduction and an overview of the series.
In the later posts of these series, we compare different migration methods to help you to understand the features, benefits, nature of complexity, trade-off's involved in each of them.
