In the associated lab we will step through another example of how to work with AWS database migration services. The goal of this lab is to become more familiar with DMS and general database concepts in AWS.

Migrating a database from one system to another can be a daunting task, but with the AWS Database Migration Service (DMS), the process can be made much simpler. In this article, we will discuss the steps involved in migrating a MySQL database to PostgreSQL using DMS.

First, you will need to set up an AWS account if you haven’t already. Once you have done that, you can log in to the AWS Management Console and navigate to the DMS page.

Next, you will need to create a replication instance. This is the server that will handle the migration process. You can choose the instance type and storage size that best fits your needs.

Once your replication instance is set up, you will need to create a migration task. This is where you will specify the source and target databases, as well as any other settings such as table mappings and data transformation rules.

With your migration task set up, you can start the migration process. DMS will begin replicating data from the source MySQL database to the target PostgreSQL database. You can monitor the progress of the migration in the DMS console.

After the migration is complete, you can test the new PostgreSQL database to ensure that all data has been correctly transferred. If everything looks good, you can then switch over to using the new database and decommission the old MySQL database.

It’s worth noting that DMS supports homogeneous migrations (e.g., MySQL to MySQL) and heterogeneous migrations (e.g., MySQL to PostgreSQL) and also supports migrating data to cloud-native databases like Amazon Aurora, Amazon RDS, or Amazon Redshift.

In conclusion, migrating a MySQL database to PostgreSQL with AWS DMS is a straightforward process that can save you a lot of time and effort. With its intuitive interface and powerful features, DMS makes it easy to migrate your data to the cloud and take advantage of the many benefits that come with it.
