Step-by-Step Tutorial: Migrating Multi-Platform Databases with dbMigration .NET

I am assuming you are a database administrator or software developer looking to migrate a production schema and its data from an on-premises Microsoft SQL Server to a PostgreSQL instance hosted in the cloud.

Migrating data between different database engines is often complex. Variations in data types, syntax, and schema structures can cause errors. dbMigration .NET simplifies this process. It is a powerful, portable tool. It supports multiple database platforms. This guide will walk you through a successful multi-platform migration. 🗺️ Prerequisites Before starting, ensure you have the following ready: Tool: Download the latest version of dbMigration .NET.

Access: Windows administrative rights to run the portable executable. Source: Connection details for your SQL Server instance. Target: Connection details for your PostgreSQL instance.

Drivers: Target database client drivers installed if required. 🔄 Step 1: Connect to the Source Database

First, establish a stable connection to your source environment. Launch dbMigration.exe. Click From on the left panel. Select SQL Server from the dropdown. Enter your server hostname. Choose your authentication method. Select your source database. Click Connect. 🎯 Step 2: Connect to the Target Database Next, define where your data will be migrated. Click To on the right panel. Select PostgreSQL from the database list. Input the target host URL. Provide the port number (default is 5432). Enter your target database name. Input your user credentials. Click Connect. 🛠️ Step 3: Configure Mapping and Schema Options

Data types do not always match perfectly between different platforms. Click the Options gear icon. Review the Data Type Mapping table. Verify how SQL Server types convert to PostgreSQL types. Check Create Table to build missing target structures. Check Include Indexes to preserve query performance. Check Include Foreign Keys to maintain data integrity. 🗂️ Step 4: Select Tables and Run Validation

Choose the specific data you want to move and test the connection. View the source schema tree view. Check the boxes next to your desired tables. Click the Validate button.

Review the validation report for potential naming conflicts. Fix reserved keyword conflicts using the renaming tool. 🚀 Step 5: Execute and Monitor the Migration Run the migration process and monitor its progress. Click the Execute (Play) button. Watch the live progress bar for active transfers. Monitor the row counts matching between source and target. Check the bottom log window for any runtime errors. 🛑 Step 6: Post-Migration Verification

Always verify the integrity of your data after the tool finishes. Open your PostgreSQL management tool (e.g., pgAdmin). Run a row count query on key tables. Compare the numbers to your SQL Server source.

Inspect random records to ensure accurate date and string formatting.
