Copy Data from SQL Server to PostgreSQL Automatically
Move data from Microsoft SQL Server to PostgreSQL without writing scripts or building complex migration processes.
Connect your databases, map and transform your data visually, then run the transfer once or automate it on a schedule.
Typical migration experience: "I installed the software, watched one short video, and had my SQL Server data migrated to PostgreSQL in about 10 minutes. I expected it to take hours."
SQL Server Data Migration Example
Read data from SQL Server, transform and map the fields, then write the results directly to PostgreSQL.

How to Copy Data from SQL Server to PostgreSQL - Step-by-Step
1. Launch Advanced ETL Processor
- Create a SQL Server Connection using server name, database name, authentication type, and credentials
- Create a PostgreSQL Connection with host, port, database name, username, and password
2. Create a New Transformation
Right-click on a transformation group and choose New to define a new workflow.
3. Configure Reader
- Double-click the reader component to open Reader Properties
- Select your SQL Server connection
- Choose a table or write a custom SQL SELECT query
4. Configure Writer
- Double-click the writer component to open Writer Properties
- Select the PostgreSQL connection
- Specify the target table and insert mode (append, truncate, replace)
5. Map and Format Fields
- Map SQL Server fields to PostgreSQL columns
- Apply necessary transformations or data type conversions
6. Run the Transformation
Click the Run button (Green Arrow). The data will be copied from SQL Server to PostgreSQL with logging, rollback, and error-handling features active.
Business usage examples
Operations lead
Move database rows through repeatable copy workflows instead of manual exports and imports.
Data team
Map fields between Access, SQL Server, MySQL, PostgreSQL, Oracle, Salesforce, and other systems.
Compliance owner
Keep source queries, target writes, run logs, and failures visible enough for audit work.
