Does the migration preserve my existing data?

Yes. When migrating to the destination database, you can choose between overwriting existing data or appending to it. The tool does not modify your source data unless you explicitly choose to.

How long does the migration take?

Migration speed depends on data volume, network connectivity, and database performance. Thanks to bulk-insert technology, ESF Database Migration Toolkit can migrate large datasets with millions of records efficiently, typically processing 10,000 to 100,000 rows per minute.

Can I migrate only specific tables or fields?

Yes. During the mapping step, you can select specific tables and views to migrate, customize field mappings, and apply data filters to migrate only the rows that meet your criteria.

Does ESF Database Migration Toolkit support Unicode and different character sets?

Yes. The tool fully supports UNICODE and automatic character set conversion between different encodings (UTF-8, CP1250, LATIN, ASCII, etc.).

Can I schedule migrations to run automatically?

Yes. ESF Database Migration Toolkit supports command-line execution and job saving. You can save your migration configuration as a job file and run it via command line, allowing automation through Windows Task Scheduler.

What happens if the migration fails mid-way?

ESF Database Migration Toolkit provides detailed transaction logging. In case of an error, you can review the log to identify problematic records, fix the issue, and resume the migration. The tool supports transactional integrity to prevent data corruption.

Troubleshooting & Common Issues

ODBC Driver Not Found

If you receive an "ODBC driver not found" error, verify that the IBM Informix ODBC driver is correctly installed. Check Windows ODBC Data Source Administrator (search for "ODBC" in the Start Menu) to confirm the driver appears in the list.

Connection Timeout

If the connection times out, check: (1) the Informix server is running and accessible from your network, (2) the server name format is correct (Server@Host), (3) the port number is correct and not blocked by a firewall.

Authentication Failure

Verify your username and password are correct. Informix uses operating system-level authentication in some configurations. Consult your database administrator if you're unsure about the correct credentials.

Frequently Asked Questions

What Informix versions are supported?

ESF Database Migration Toolkit supports IBM Informix IDS 11 and later versions. Check the features page for the latest compatibility information.

Do I need to install anything besides the ODBC driver?

You only need the IBM Informix ODBC driver installed on the same machine where ESF Database Migration Toolkit is running. The program handles the rest automatically.

Can I migrate data from Informix to other databases?

Yes. Once connected, you can migrate data from Informix to any supported destination database, including SQL Server, Oracle, MySQL, PostgreSQL, and more.

What if I can't connect to the Informix server?

Verify that: (1) the Informix server is running and accessible from your network, (2) the ODBC driver is properly installed, (3) the server name, host, port, and credentials are correct, and (4) firewall rules allow outbound connections to the Informix port.

Can I connect to Informix on Linux/Unix from Windows?

Yes. ESF Database Migration Toolkit runs on Windows and can connect to Informix servers running on any platform (Windows, Linux, Unix) as long as the network connection and ODBC driver are properly configured.
