Stellar Converter for Database: Complete Migration Guide Database migration is a critical task for any organization. Moving schemas, tables, and records between different database management systems (DBMS) often introduces risks of data loss, corruption, and extensive downtime. Stellar Converter for Database simplifies this process by providing an automated, graphical interface to convert database files from one format to another with high precision.
This guide provides a comprehensive walkthrough on how to use Stellar Converter for Database to achieve a seamless migration. 1. Supported Databases and System Requirements
Before beginning the migration, ensure your source and target environments are compatible with the software. Supported Database Platforms
Microsoft SQL Server: MS SQL (.mdf) files and live instances. MySQL: Live databases and source files. SQLite: .db and .sqlite database files.
PostgreSQL: Direct conversion to and from PostgreSQL instances. Interbase: Support for .gdb and .ib files. MariaDB: Full schema and data migration compatibility. System Requirements
Operating System: Windows 11, 10, 8.1, 8, 7, or Windows Server 2016, 2012, 2008. Processor: Intel-compatible (x86, x64).
Memory: Minimum 4 GB RAM (8 GB recommended for large databases). Hard Disk: 250 MB of free space for software installation. 2. Pre-Migration Checklist
To ensure a smooth transition and eliminate data loss risks, complete these preparatory steps:
Take a Full Backup: Always generate a fresh backup of your source database before introducing third-party migration tools.
Verify Access Privileges: Ensure the database user account used for migration has structural read permissions on the source and write permissions on the target database.
Check Target Disk Space: Ensure the target server or storage drive has enough capacity to accommodate the newly migrated data and index structures.
Install Prerequisites: Install necessary database drivers (such as OLEDB or ODBC drivers) if required by your specific database types. 3. Step-by-Step Migration Process
Stellar Converter for Database uses a wizard-based interface. Follow these steps to execute your migration: Step 1: Select the Source Database Launch Stellar Converter for Database.
A database selection window will appear. Choose your Source Database Type from the dropdown menu (e.g., MS SQL, MySQL, SQLite).
Choose whether to browse for a offline database file (.mdf, .db) or connect to a live database instance.
Input your server credentials (Host, Database Name, Username, and Password) if connecting to a live instance, then click OK. Step 2: Scan and Preview Data
The software will automatically scan the source database structure.
Once the scan finishes, a tree view of the database components appears in the left pane.
Click on individual tables, views, triggers, or stored procedures to preview the records and schema details in the right pane. This verifies that the software has read the data correctly. Step 3: Configure Target Database Settings Click the Convert button on the main toolbar.
A configuration window will open. Select your Target Database Type (e.g., converting MS SQL to MySQL). Provide the destination server details: Server Name / IP Address Authentication Type (Windows or Server Authentication) Username and Password
Select whether to create a brand new database on the target server or append the data to an existing database. Step 4: Execute the Conversion Click Convert to initialize the data transfer.
Monitor the real-time progress bar showing the table-by-table migration status.
Once completed, a confirmation dialog box reading “Conversion Process Completed Successfully” will appear. Click OK. 4. Post-Migration Verification
After the software finishes the data transfer, complete these validation steps before routing live application traffic to the new database:
Row Count Verification: Run COUNT(*) queries on critical tables in both the source and target databases to verify that all records migrated.
Check Data Types: Inspect how specialized data types (like BLOBs, Clobs, or custom date formats) mapped to the new database architecture.
Validate Constraints: Confirm that primary keys, foreign keys, unique constraints, and default values are active on the target schema.
Recompile Application Code: Update your application connection strings to point to the new database instance and perform integration testing. 5. Troubleshooting Common Issues
Connection Errors: If the software cannot connect to the source or target server, verify that the remote database server allows TCP/IP connections and that local firewalls are not blocking the database port (e.g., port 1433 for MS SQL, port 3306 for MySQL).
Collation Mismatches: If text characters appear corrupted post-migration, verify that the target database character set matches the collation properties of the source database.
Large File Timeouts: For databases exceeding several hundred gigabytes, temporary network timeouts may occur. Running the software directly on the target or source server hardware eliminates network latency bottlenecks.

Do you need focus on a specific database pair (e.g., MS SQL to MySQL)?
Should I include advanced command-line automation instructions?
What is the target technical audience (e.g., beginners or advanced DBAs)?
I can adjust the technical depth and add specialized code snippets based on your requirements.
