Automating SQL Server Database Migration for DevOps Implementation
Frequently, the process of migrating a database can be laborious. It requires managing alterations made to both the database schema and its data. To establish a dependable automation process, it’s essential to have a comprehensive understanding of the migration process and use appropriate tools to increase efficiency.
Large and successful organizations nowadays prioritize the swift and efficient implementation of changes in their applications. Their goal is to achieve maximum efficiency with minimal effort. To attain this level of efficiency, corporations need to establish a seamless workflow where the entire development process runs smoothly and remains under control. Organizations often adopt the agile development methodology to deliver the necessary changes as fast as possible while ensuring high standards.
This approach allows for planning, coding, and building applications at a rapid pace. In addition to this specific approach, other common practices employed by organizations include continuous integration and continuous delivery. While continuous integration helps to incorporate quality assurance into agile development, continuous delivery is designed to smoothly integrate releases and continuous integration.
To merge software development with IT operations, companies opt for DevOps. This model proposes that the processes related to the technology infrastructure of an application should be performed automatically rather than manually.

Migrating Databases using DevOps
CI/ CD, and DevOps practices greatly enhance application development and expedite software operations. It’s common for developers to work with various applications and databases and require copies of databases for use in development environments. DevOps practices are vital in this regard since they facilitate rapid changes while ensuring minimal risk of application downtime and data breaches. Despite the many benefits of integrating database changes into DevOps, it can still be challenging to synchronize database modifications and apply various development techniques.
Apps vs Databases
There is a significant contrast between the actions required to update a database and those needed to update an application. Database changes cannot be merely overwritten; modifications must be made to the database structure itself. This means that it’s impossible to modify the database structure while simultaneously preserving the data.
In addition to this, one must integrate database data changes into work environments. Unlike applications, databases are not composed of a set of files that can be easily transferred through work environments via copy-and-paste. They consist of a data container that must be maintained and protected. Thus, to implement changes, a transition code must be devised to carefully manage changes to both the database structure and data.
The Code Nature of Databases
A database comprises a collection of structural components and data. The structural components consist of a database schema, tables, stored procedures, and triggers. Although these elements can be easily modified in a development environment, introducing changes in a production environment follows entirely different rules.
Integrating DevOps practices into databases helps treat database changes as code. You can identify changes in the source repository, execute the code to apply changes and automate the implementation of these changes to databases. The automation of all stages involved in the database lifecycle, including development, testing, staging, and production, significantly speeds up the process and makes it more comprehensive, clear, and systematic. Therefore, it’s crucial to provide teams with relevant information about database automation tools to achieve full implementation of the DevOps workflow.
Comparing and Synchronizing Databases
Using a traditional version control system to handle code for database changes can be ineffective and unstable when it comes to automation. Therefore, it’s much better to create transition codes between database environments using comparison and synchronization. This approach enables rapid detection of data and schema differences between the source and target environments, with automatic implementation.
Manual Migration of Databases
Performing manual database migration between two environments involves the following steps:
- Identifying the differences in the database schema between the source and target environment.
- Creating necessary SQL scripts for synchronization.
- Executing the SQL scripts against the target environment.
However, despite the possibility of this approach, its reliability and accuracy remain uncertain. Human error is a significant factor that cannot be overlooked, as it can occur during one or several phases, resulting in application downtime or data safety compromise. Additionally, performing these actions manually significantly slows down the delivery of changes and undermines the quality of databases.

Automatic Database Migration
Automated database migration can eliminate the downsides of manual migration, including reduced productivity and speed. By automating the migration process between different environments, you can:
- Streamline the migration process.
- Reduce the need for multiple teams to participate in database migration between their respective environments.
- Implement consistent migrations across different environments.
- Ensure high standards and consistency in migration results.
- Increase the likelihood of successful migration. You can test the automation between internal environments before applying it to or from a production environment.
- Manage different scopes of migration, from single-task migrations to large migrations involving multiple databases.
- Allow other specialists to review, modify, and reuse the automation code.
Integrate Database Automation
The benefits of database automation far outweigh the drawbacks, making it worthwhile to note that the automatic migration of databases can also be integrated with other software tools. In addition to the capabilities mentioned above, organizations can achieve end-to-end automation for DevOps. This enables building servers, change management, issue tracking, and delivering releases, incorporating these processes into automatic database migration. As a result, companies can deploy databases automatically, provide smaller and safer deployments, identify errors at early stages and eliminate them, enable developers to create error-free code and respond quickly to the company’s demands.
The dbForge Compare Bundle for SQL Server facilitates the integration of a SQL Server database into the DevOps process by enabling automatic synchronization of the database schema and data for successful deployment. The bundle comprises two individual tools, namely dbForge Schema Compare and dbForge Data Compare.
