Our Database Migration Services
If you are replacing an old system and need to import your existing database, we provide migration services. Belitsoft ensures smooth data transition to new databases, on-premises or cloud. Advanced database migration tools help us achieve your business goals.
Transferring a database from one cloud service to another. For instance, migrating from Amazon RDS to Azure SQL Database.
Moving a database from a company's own servers to a cloud-based service. Examples include migrating from a local SQL Server to Amazon RDS or Azure SQL Database.
Migrating databases from one type of database system to another, such as from MySQL to PostgreSQL. This can occur in the cloud and on-premise contexts.
Advantages of Database Migration with Belitsoft
Belitsoft is one of the highest-rated data migration IT companies. Our database migration services focus on both moving your data and redesigning or upgrading your database architecture so your data delivers more value for your business. Choose Belitsoft for your database migration needs and experience a seamless transition with no downtime.
Integration with Modern Technologies. Partnering with Belitsoft for your database migration gives you access to platforms that performs computations unavailable in legacy systems. Your new software will handle unstructured data, support geospatial data for location-based queries ("Find all customers within 5 km of this store") and graph data to analyze business relationships. Belitsoft can set up your database to check for fraud in real time, enabling transactions to be verified in milliseconds. We can also prepare your database to run AI models. This may include vector search and semantic similarity search, so you get advanced retrieval capabilities similar to modern AI systems but on your data. After training ML models (with BigQuery ML, PostgresML, or SQL Server Machine Learning Services), you will be able to run predictions.
Enhanced Security. Cloud databases automatically encrypt data both when stored on their servers and during transmission. Cloud database providers (including Amazon and Microsoft) automatically patch vulnerabilities, so you do not have to worry about missed software updates.
Using Role-Based Access Control, Belitsoft will help you set up highly specific access rules ("Marketing staff can view customer names but not credit card information") and configure trigger alerts when someone attempts to access protected data outside of specified rules, with detailed logs ("User John accessed the Salaries table at 3:42 PM on Tuesday from 'Country name') and block the data or ban the user account with cloud security features.
Potential Cost Savings. Renting capacity in the cloud can be more affordable than buying capacity on-premises: you avoid paying for idle machinery, electricity, cooling, and human labor. Amazon or Google pays the electric bill, installs air conditioning, replaces broken hard drives, and upgrades hardware as it ages. These costs are bundled into your subscription, but cloud providers operate at massive scale, so it is often cheaper than managing these expenses yourself. Belitsoft helps you move to the cloud and optimize your usage, making cloud operations less expensive for you than owning hardware to achieve the same business results.
AUTO-SCALING DATABASE. Belitsoft helps businesses with unpredictable or seasonal usage patterns deploy scalable databases. A scalable database can increase its capacity (storage, processing power, or speed) to support higher workloads and reduce its capacity when demand drops. For example, a ticketing website database may receive thousands of requests per second when sales open for a major concert, or an agricultural marketplace may face data surges during the autumn harvest. Belitsoft ensures that your database scales to prevent system crashes during peak periods and protects your revenue.
Database Migration Process by Belitsoft
We offer a range of database migrations to suit your business needs. Whether full or partial, we'll take care of your data transfer. This includes both database migration consulting services and platform transitions like Power BI Premium migration to Microsoft Fabric to modernize BI infrastructure with minimal disruptions. Our team of experts ensures your data remains secure and accessible.
| SOURCE DATABASE ANALYSIS: | We analyze your current database state (source database, its size, 'large' tables, and data types) and business requirements to select tools and a migration strategy aligned with your future goals |
| TOOL SELECTION: |
We choose the right migration tool for your specific needs and setup, including language-specific frameworks (Entity Framework, etc.), database-native tools (SQL Server Migration Assistant, etc.), or independent migration platforms like AWS DMS, etc. |
| DATA ASSESSMENT: | We profile your data to identify quality issues (inconsistencies, duplicates, orphaned records, and integrity violations). Then we establish data quality rules and cleansing procedures to ensure clean migration and reduce the risk of delays, budget overruns, and failures. |
| MIGRATION STRATEGY DESIGN: | Our migration plan covers the transfer approach, data transformation rules, and rollback strategy. Belitsoft's Our data migration plan details transfer approach, transformation logic, and rollback strategy. Belitsoft's database developers adjust your database structure as your project evolves through planned schema migrations and version control. |
| SCHEMA MIGRATION: | We move all elements of the database structure to the new system in the correct dependency order: tables, indexes, constraints, views, stored procedures, triggers, and permissions. Your new database system will support everything your old one did and get advanced capabilities through database modernization. |
| DATA MIGRATION: | We extract data from your source database, transform it to match the new schema and business rules, then load it into the target system. Belitsoft ensures complete data transfer with no duplicates created. |
| TEST MIGRATION: | We run an initial migration with sample data to validate our process and catch issues before the full migration. |
| VALIDATION and LIVE TEST: | Our validation ensures proper function and performance. This phase is iterative: we load some data, do some functional and performance evaluation, and repeat the process. Once confident in validations, we're ready for production. We test data migration with live data for real-world scenarios. |
| PRODUCTION CUTOVER and POST-MIGRATION VALIDATION: | We verify data completeness, application functionality, and system performance in the production environment to confirm migration success. |
| OLD DATABASE RETIREMENT POLICY: | After a successful migration, we develop a retirement policy for the old database, if required. |

Technologies and tools we use
Each migration project is unique and at Belitsoft, we select tools based on your requirements. We aim to migrate your database seamlessly and efficiently, minimizing downtime and maximizing productivity with top tools.
We perform AWS migrations with minimal downtime both homogeneous (within the same platform) and heterogeneous (to another platform). Replicating data across multiple Availability Zones (AZs) ensures uninterrupted application operation during migration. For large migrations like terabyte-sized databases, AWS DMS ensures no data loss and low expenses. You pay only for compute resources and log storage used.
We utilize Azure cloud migration for clients looking to migrate to Azure. Prior to migration, we identify requirements and then estimate the cost of running your workload in Azure. We migrate your databases to Azure, ensuring a comprehensive and scalable process that includes data, schema, and objects from multiple sources. Your database and server objects, along with user accounts and agent jobs, migrate completely.
Best Practices for Database Migration by Belitsoft
Small, Manageable Changes
Belitsoft is a data migration vendor offering low‑risk incremental migration. We use a gradual approach in data migration. By taking manageable steps, we reduce the risk and make the migration process easier to handle and troubleshoot.
Separation of Concerns
We structure applications to separate different functionalities, minimizing the risk associated with changes during migration.
Single Responsibility Principle
We group related parts of your code together, as they are likely to change together during database migrations. This principle keeps your code organized and manageable.
Decoupling Release from Deployment
We use feature flags to decouple the release of new features from their deployment, which is crucial due to potential risks like downtime and data loss during database migration.
Feature Flagging the Data Access Layer
We strategically employ feature flags to ensure a controlled and gradual data migration. A simple toggle or complex multivariate flag can do this.
Avoiding Ground-Up Redesign
We check your design before data migration to avoid a complete redesign. We separate functionalities to minimize change and group related code together.
Minimizing Downtime
Time equals money in business. That's why we aim for near-zero downtime during database migrations. Our team guarantees uninterrupted business operations during migration.
Implementing a Kill Switch
We have a kill switch to instantly revert to the old database in case of any migration issues, ensuring data and operations remain secure.
Progressive and Strategic Release
We gradually increase traffic to the target database while conducting scalability testing to prevent overload. Simultaneously, strategic traffic direction, like beta-testing with a subset of users, targeting based on geography, device, or identity and stakeholder validation, ensures a smooth transition with minimized risks and thorough testing and validation at every stage.
Leveraging Version Control Systems (VCS)
We maintain a detailed history of changes to keep your target database and code compatible. This system helps us efficiently resolve conflicts, like changes to the same part of the database. We store this history with your code for easy management.
Frequently Asked Questions
- Your database is too slow. More users, data, and transactions have worn it out. Queries take too long. Users get timeouts. You need a more scalable system.
- You are running on outdated technology. Your old database does not have the features needed today: cloud integration, auto-scaling, better security controls. Old systems are hard to patch and maintain. They are harder to keep compliant in regulated industries like finance and healthcare.
- Your database is the wrong one for your needs. You need a different kind. For example, you used a relational database for unstructured data, or you used the wrong database for analytics.
- Costs are too high. Testing new features on an expensive license is costing too much money as you grow. Or you are locked into a certain cloud provider. Moving to other cloud companies can cut costs and give you more options.
- You have new rules to follow. They require security features, audit logs, and compliance certificates. Your current database does not provide what you need to meet regulations.
Database migration is the process of migrating data from one or more source databases to one or more target databases by using a database migration service. When a migration is finished, the dataset in the source databases resides fully, though possibly restructured, in the target databases. Clients that accessed the source databases are then switched over to the target databases, and the source databases are turned down.
Seek assistance from qualified specialists for best migration results. Collaborating with experts helps prevent issues such as data loss or corruption.
- Preventing data loss. Fear of data loss is a serious concern during database migration. Before migration, we adopt rigorous data backup and recovery strategies to minimize risk. Our team of experts thoroughly tests each migration in a safe, isolated environment before applying it to the actual database. Your data is secure and can be swiftly restored in the event of an issue.
- Securing your data. During a database migration, data security can be vulnerable if handled incorrectly due to non-compliance, inadequate access controls, or data exposure during transit. We encrypt all data before the migration process and maintain strict access controls to prevent unauthorized access and data breaches.
- Managing multiple databases. Large companies often have separate databases in various departments. At Belitsoft, we simplify this complexity. We audit databases and create detailed migration plans. Plan ensures consistency and accuracy by converting schemas and normalizing data.
- Navigating complex migration strategies. Selecting a database migration approach is difficult due to data complexity, large database size, system differences, need for data integrity, compliance regulations, and high-level technical expertise. At Belitsoft, we conduct comprehensive research and analysis to understand every detail. We devise a customized plan for migrating your database.
Migration tools are software applications that help manage database migrations. Database migration tool choice depends on project needs, database systems, and preferred migration strategy (state-based or change-based). Once the migration starts, we recommend using a single tool to avoid complications.
Homogeneous vs Heterogeneous
- Homogeneous database migration. We offer homogeneous database migrations. This process involves moving your application and its data from one database to another while keeping the underlying Database Management System (DBMS) consistent. For instance, we can help you transition from an on-premise SQL Server to an Azure-hosted SQL Server, or from PostgreSQL hosted in EC2 to PostgreSQL on Amazon RDS. This migration strategy is effective for cost optimization, cluster consolidation, and transitioning from data centers to cloud-based solutions.
- Heterogeneous database migrations. This service involves transitioning your application and its data from one database to another, with a change in the underlying Database Management System (DBMS). For example, we can facilitate your migration from Microsoft SQL Server to PostgreSQL, or from PostgreSQL relational database to DynamoDB. Businesses opt for heterogeneous database migration for improved capabilities, scalability, performance, and cost optimization, especially when transitioning to cloud-native databases.
Active-Passive vs Active-Active
For your business needs, we offer active-passive or active-active migration.
- During an active-passive migration, we modify the source database while the target database is in read-only mode.
- In active-active migration, both databases can be modified.
State-based vs Change-based
These are two main types of database schema transformation strategies.
- State-based database migration creates artifacts for rebuilding the desired database state from scratch.
- Change-based database migration builds on a previous database state to define operations to achieve a new state.
