Convert PostgreSQL to SQL Server.

Using our DBConvert/DBSync applications you can easily synchronize and convert your databases from PostgreSQL to Microsoft SQL Server or to Windows Azure SQL Databases. Amazon RDS PostgreSQL / Heroku Postgres instances as a source or target are also supported. Our wizard-Style interface will guide you through all the steps of performing migration and replication jobs easily and effectively.

In scenarios where you have any server restrictions, you can create MS SQL Dump file with all data out of your PostgreSQL database.

Our software will save you many hours of learning SQL commands since any large PostgreSQL database can be converted approximately in 5-10 minutes.

The DBSync application performs synchronization and replication from a PostgreSQL source to Microsoft SQL Server smoothly due to

three synchronization types (Drop, Insert, Update).

Additionally, our built-in scheduler lets you to launch automatically, with no interaction required from you.

Using PostgreSQL to SQL Server conversion and synchronization tools.

When you start DBConvert or DBSync application in GUI mode it guides you through several steps to set up the database migration or synchronization:

1. Connect to PostgreSQL source database.

If a source database requires you to log in, you can specify a user name/ password and host/ port parameters.

Connect to PostgreSQL source database from DBConvert

2. Connect to SQL Server destination database.

Specifying parameters for destination database looks like the same as for source. Usually, it consists of defining connection settings and username/password pairs.

Connect to SQL Server target database from DBConvert

NOTE #1: Every DBConvert or DBSync tool has two different databases in its name. That means any specified database from a pair can be set up as a source or destination. Besides, the same type of database may be set up both as a source or destination.

As an example, here is the list of possible migration directions with on-premises databases:

  • PostgreSQL to SQL Server
  • SQL Server to PostgreSQL
  • PostgreSQL to PostgreSQL
  • SQL Server to SQL Server

NOTE #2: Don't be confused by the fact that connections to cloud databases like Amazon RDS, Google Cloud, and Heroku are not explicitly specified in the configuration of a source or destination in the DBConvert / DBSync interface. To connect to Cloud database instances, use the same settings as you do for traditional on-premises databases.

NOTE #3: Your connections to source and target databases stay active until you close DBConvert/ DBSync application or reopen new connections on "source" and "destination" steps.

Read more about the specific source/ destination configurations for different databases.

3. Custoimzation and configuration.

At the next step, you can specify precisely which tables, fields, indices, views you want to transfer to the SQL Server destination database. Just check/ uncheck the box in front of each database object you want to convert.

Customize general database/ tables settings. Or set up a particular table , field, index individually when migrating data from PostgreSQL to SQL Server.

Check out our articles about Custoimzation and configuration. for detailed information.

The screenshot below sums up general features available in DBConvert software solutions.

4. Detection of potential database migration issues. Errors and Warnings

The database typically constrains certain relations on the data that cannot be violated. On the customization step, a smart error checker verifies all possible Data integrity and Referential integrity issues and highlights them, if any, before performing a migration.

By default, DBConvert tries to automatically map the database types of the source PostgreSQL database to the closest equivalent of the target SQL Server database types. However, you can manually change the data types for the entire database globally using the "Global mapping" or individually for each field.

Check out Smart error checker. Errors and Warnings for more information.

5. Execution. The final stage of data migration from PostgreSQL to SQL Server

Once you configure source and destination databases for migration in the previous steps, you can start the actual conversion or synchronization process.

Click the "Commit" button to start conversion. Also, here, you can monitor the migtation/ synchronization process.

Optionally save connection settings and configuration parameters into the session file to schedule the launching of sync or migration jobs regularly.

Command line mode

Previously saved sessions can be passed as parameters to Command-Line DBConvert Client. A session keeps PostgreSQL source and SQL Server target database connection settings with other specified options.

Example: C:\Program Files\DBConvert\mssql2postgresqlPro\mssql2postgresqlPro_Cons.exe /Session:"Session_Name"

NOTE: First, you have to run the software in GUI mode to create a session file with initial parameters.

Built-in scheduler.

Our applications come with a built-in scheduler to run database migration and sync jobs at specified times. Just set the scheduled date and time to execute job sessions automatically.

Supported OS:


  • Necessary privileges to write into database on the target PostgreSQL server (this requirement is optional as there is an option to overcome the restrictions using dump file or PHP Script)
  • Necessary privileges to write into database on the target SQL Server (this requirement is optional as there is an option to overcome the restrictions using dump file)
