Migrate MySQL to SQL Server Database – Best How to Guide

There can be multiple reasons as to why a user may wish to migrate MySQL to SQL Server database. This migration is a crucial step for businesses or organizations, who are looking for a way to enhance their scalability and security. But this process may not be as simple as it looks. 

This article will help us discuss the same issue and the challenges a user may face while migrating the MySQL Server. We will also provide a solution using which a user can easily carry out the migration process. Let’s begin by understanding the reasons for this migration.

Why Do We Need to Migrate MySQL to SQL Server?

As we said earlier, there can be various reasons that call for this migration. Some of these reasons are mentioned here.

• For Better Performance and Scalability: One of the reasons for the migration is better performance and higher scalability offered by the SQL Server. 
• For Enhanced Security: SQL Server provides much advanced security features. These enhanced security features allow the users to protect their crucial and sensitive data from any data breach.  
• For Numerous Advanced Features: Along with the security and performance advantages, the SQL Server offers various features like better integration with the Microsoft products, efficient and secure backups, and advanced software updates. 
• Better Compatibility: For organizations that work on Microsoft-based environments, MySQL to SQL Server migration will offer better cross platform compatibility. 
• Simpler Database Administration: if we talk about availability, MySQL has a limited set of tools. On the other hand, SQL Server offers a wider range of tools like Azure Data Studio and SSMS that can help with management of the databases efficiently. 

All these reasons become a factor to migrate MySQL to SQL Server. But during the migration process, there are certain challenges a user may face. Let’s take a look at what these challenges are and how to resolve them. 

What Are the Obstacles in the MySQL Database Migration Process?

When a user convert MySQL to SQL Server database, they encounter different obstacles that can make the process much more complex and unreliable. These challenges are:

• Varied Data Structures: Both MySQL and SQL Server have different methods and structures for storing data in their databases. This might become a challenge for the users while during the MySQL migration. 
• Process Downtime: If the user needs to migrate larger databases from MySQL, it can take a lot of time and may lead to system downtime. 
• Compatibility Issues: There are some applications that rely on MySQL working and behavior. To work on those applications after the migration, you might have to change the application’s configuration accordingly. 
• Security Differences: Both MySQL and SQL Server have different security configuration and workings. After the migrations process, it is required to add the new users and permissions, which can be a bit complex due to the security differences. 

Similarly, there are other challenges that can trouble the users during the migration process. To make the process simpler, we have the SSMA tool. By using this tool, users can easily migrate MySQL to SQL Server 2012/2016/2014 database. Let’s take a look at how this method works.

Migrating MySQL Database Using SSMA – Overview

The method we are going to discuss is to carry out the migration using SSMA. So what is this SSMA that we keep on repeating? Let’s take a closer look at SSMA now.

Key Features of SSMA

• It allows schema conversion during the migration process.
• It allows the user to migrate from MySQL to Azure SQL.
• The tool makes the migration process easier by automating various tasks like object creation, schema conversion, etc.  
• Additionally, it offers efficiency through the process and also provides compatibility checks before the migration process to detect any possible issues beforehand. 
• The tool makes the process to migrate MySQL to SQL Server efficient by minimizing the risk of data loss and maintaining the data integrity through the process. 
• SSMA also helps with object creation by creating the important objects like views, functions, tables, etc. in the destination server.
• Even if during the process, any error occurs, SSMA offers to detect, report the error and allows you to resolve them during the migration process. 

Steps to Migrate MySQL to SQL Server Using SSMA

# To install the software

1. To download SSMA go to the official Microsoft website https://www.microsoft.com/en-us/download/details.aspx?id=54257 .
2. Select the software version before installation.
3. Double click on the file that downloaded and then click on the next button.

6. Enable the telemetry and automatic update options and then click on the install button. 
7. The installation process will take time. Once the file is installed, click on the Finish button. 
8. After following these steps, you have successfully downloaded the SSMA.
9. Now let’s proceed with the steps to convert MySQL to SQL Server database.

# In SSMA

1. Open the software and select the Create New Project option.
2. Add the project name and choose a destination path. Also, choose the version of the SQL Server the database will be migrating to. 
3. Click on Connect to MySQL option and then enter the required details and then click on the Connect button.
4. A list with the MySQL Database will be displayed, choose the database that needs to be moved. Click on the OK button. 
5. Now move to Connect to SQL Server option for connecting to the destination database. Then add the required credentials.
6. Choose the database to be processed and then click on Migrate Data to initiate the migration process. 
7. A new connection request will show up for MySQL. Click on the Connect Button.
8. A new SQL Server Connection is required. Press the Connect Button. 
9. After completing these steps, the data will be displayed in SQL Server.

By following these steps, you can migrate MySQL to SQL Server 2012/2014/2016 and other compatible versions more efficiently.

Things to Keep in Mind During MySQL to SQL Server Migration

There are certain things a user should keep in mind for a smooth migration. There are many factors one should consider while carrying out the database conversion process. Let’s understand these factors one by one. 

• Before the Migration Process
  
  • Take Backup: Before beginning the migration process, it is important to take a backup of the database. In case the migration process affects the database, the backup will help to recover the data. 
  • Learn the Differences: Both MySQL and SQL Server have their own abilities and limitations. Before migrating the database, it is important to learn and understand these differences to prevent any possible errors. 
  • Environment Preparation Before Migration: Before starting the process to convert MySQL to SQL Server, it is important to prepare the SQL Server accordingly. Make sure that the destination server has sufficient disk space to store the source database. 
• When the Process Takes place
  
  • Reliable Migration Tool:  To run a smooth migration process, it is important to use an efficient migration software. SSMA is a reliable and trustworthy tool for the MySQL database migration.  
  • Track and Monitor the Migration Process: It is important to keep an eye on the migration process to look for any issues or error messages.
    
    
• After MySQL to SQL Server Migration Ends
  
  • Test and Validate: After the migration process finishes, do a thorough database testing to ensure no data loss and to check if the database is working properly. 
  • Maintain Migrated Database: It is necessary to maintain the database after the migration. One can maintain the database by regularly checking up for any errors or issues in the database. 

Conclusion

Migrating data from one database to another database is one thing, but when it comes to the MySQL to SQL Server migration, that’s where things get complex. But not to worry, we are here with a solution that will help you with the migration process in a simplified way.
