Method 2: Export Data from Azure MySQL to Redshift File Using CSV File 

To convert Azure MySQL to Redshift, you first need to export your Azure MySQL data into a CSV file. Then, upload the CSV file into Amazon S3 Bucket, where it’s imported to your Redshift instance. 

Step 1: Export Azure MySQL Data to a CSV File

You can export Azure MySQL data to a CSV file using MySQL Workbench. 

Prerequisites

• Connect your MySQL workbench to your MySQL database, which is hosted on Azure. 
• Provide details on setting the connection, such as the username and password.

You can access the Data Export Wizard from the Navigator pane on your MySQL Workbench to export data to a CSV File. 

Follow the steps below: 

• Go to the Navigator Pane and select the Data Export Wizard. 
• Select all the schemas you want to export to the CSV file in the Data Export window. 
• Choose a database object to export and configure the other related options. 
• Select Refresh to load all the objects that are present.
