Conversion and Synchronization

Access to PostgreSQL Conversion

DBConvert & DBSync for Access and PostgreSQL helps convert and synchronize data quickly and easily between Microsoft Access and PostgreSQL-compatible databases, supporting both on-premises and cloud deployments.

Open Source Enterprise Solution

Migrate to PostgreSQL's powerful, free, open-source database platform that provides enterprise-class features without licensing costs.

Why Migrate from MS Access to PostgreSQL?

Access serves small teams well, but PostgreSQL offers enterprise-grade capabilities for growing organizations

Microsoft Access PostgreSQL
Licensing Costs: Requires Microsoft Office license with ongoing subscription costs and deployment restrictions.
Entirely Free: Open-source database with no licensing fees, no runtime costs, and unlimited deployment rights.
Data Volume Limits: Performance degrades with large datasets, typically limited to 2GB maximum database size.
Large Data Handling: Efficiently manages terabytes of data with advanced indexing, partitioning, and optimization features.
Limited Concurrency: Not designed for more than a handful of simultaneous users effectively.
Multi-User Access: Advanced MVCC architecture supports thousands of concurrent users with excellent performance.
Platform Restriction: Windows-only desktop application limiting deployment flexibility and scalability options.
Cross-Platform Support: Runs on Windows, Linux, macOS, and various cloud platforms with flexible deployment options.
Basic Data Protection: Limited backup and recovery options with basic data integrity features.
Advanced Data Integrity: Superior backup management, point-in-time recovery, and robust data validation features.

Advanced Migration Features

Comprehensive tools for seamless Access to PostgreSQL database conversion and synchronization

Automatic Query Conversion

MS Access queries are automatically migrated to PostgreSQL views without knowing the differences between SQL dialects.

Flexible Export Options

Save data as PostgreSQL dump files or PHP scripts to bypass server access restrictions and enable flexible deployment.

Bi-directional Synchronization

Robust two-way database synchronization between Access and PostgreSQL with multiple synchronization types.

Selective Migration

Migrate entire databases or select specific schemas, tables, queries, fields, indexes, and foreign keys during setup.

Complete Structure Transfer

All database elements including table structures, relationships, indexes, and data are transferred smoothly with preservation of data integrity and constraints.

Reverse Conversion

PostgreSQL to Access

Using Access to PostgreSQL Tools

When launching the DBConvert or DBSync application in GUI mode, it seamlessly guides you through the steps to initiate database migration or synchronization:

1

Connect to Access source database

Specify the username/password and host/port parameters if your source database requires login credentials.

Connect to Access source database from DBConvert
2

Connect to PostgreSQL destination database

Specify parameters for the destination database similar to the source, defining connection settings and username/password pairs.

Connect to PostgreSQL target database from DBConvert

NOTE #1

Each DBConvert or DBSync tool's name comprises two different databases, enabling any specified database to operate as the source or destination. Furthermore, the same type of database can function as both the source and destination.

NOTE #2

Connections to cloud databases (e.g., Amazon RDS, Google Cloud, or Azure SQL) aren't explicitly specified in the user interface but use the same settings as traditional on-premises databases.

NOTE #3

Connections to source and target databases remain active until you close the DBConvert/DBSync application or reopen new connections.

Refer to our documentation for specific source/ destination configurations for different databases.

3

Configure database migration options

Specify the tables, fields, indices, and views you want to transfer to the PostgreSQL destination database by checking/unchecking the corresponding boxes.

Customize general database/ tables settings. Or configure specific table, field, index object individually when migrating data.

Explore our articles in the user's manual about Configuring database migration options for detailed information.

4

Detection of potential database migration issues

The database enforces certain relations on the data, and on the customization step, an intelligent error checker verifies all possible data integrity and referential integrity issues. It highlights any problems before migration starts.

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

Explore the Intelligent error checker for more information on errors and warnings.

5

Execution - The final stage of data migration

Initiate the conversion or synchronization process after configuring source and destination databases in the previous steps.

Click the "Commit" button to start conversion. Here, you can also monitor the conversion/synchronization process.

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

DBConvert Software Features

Command line mode

Pass previously saved sessions as parameters to the Command-Line DBConvert Client. A session retains Access source and PostgreSQL target database connection settings with other specified options.

Example:

C:\Program Files\DBConvert\access2postgresqlPro\access2postgresqlPro_Cons.exe /Session:"Session_Name"

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

Built-in scheduler

Our applications include a built-in scheduler to run database conversion and sync jobs at specified times. Set the scheduled date and time to execute job sessions automatically.

Find more Information about the built-in scheduler.

System Requirements

Ensure your system meets these requirements for optimal performance

Supported OS

Requirements

  • 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)
  • Access 2000 or higher. Both Access 32/64 versions are supported
  • Microsoft Visual C++ 2010 x86 Redistributable package
