Frequently Asked Questions

Ispirer's proprietary solution, SQLWays, automates the database migration process. It converts your schema — including tables, stored procedures, functions, and triggers — to your chosen target technology. You get high-level automation that minimizes manual coding, preserving your business logic and structural integrity as you migrate from legacy systems to modern environments like PostgreSQL or cloud-native databases.
SQLWays is a customizable solution. If you have unique project needs and scope, feel free to reach out for a free consultation. We will propose an optimal roadmap combining automated migration and expert services.

For data migration, we offer Ispirer Data Migrator (IDM). This solution establishes a direct, high-speed connection between your source and target. It utilizes parallel processing and multithreading to move massive datasets. You experience near-zero downtime thanks to iterative sync processes that capture ongoing changes while the migration runs in the background.

We breathe new life into legacy applications by converting them to modern languages and architectures. Our CodeWays solution handles the conversion of application code (such as PowerBuilder or Delphi to .NET or Java), embedded SQL statements, and database APIs. This comprehensive approach ensures your application functions correctly on the new platform without requiring a complete rewrite from scratch.
Reach out to discuss your unique migration scenario and the full range of services you might need to modernize without reinventing the wheel.

Our pricing is license-based, license prices depend on the project size and its duration. Thus, the project price is determined only after a thorough analysis of the source database or application. For this purpose, we have free Assessment Tools that will automatically collect all the necessary information.

Yes. IDM utilizes sophisticated Change Data Capture (CDC) logic through its iterative migration process. It captures inserts, updates, and deletes on the Oracle side using modification statistics and flashback queries. By repeatedly syncing these changes in background iterations, the tool minimizes lag, replicating data in near-real-time until you are ready for the final cutover.

Ispirer Toolkit supports a majority of legacy and modern applications and databases. You can choose the required migration direction on the Application Conversion and Database Migration pages.

IDM is a specialized solution for high-performance migrations from Oracle RDBMS (version 10 and above) to PostgreSQL RDBMS (version 14 and above). It handles large-scale projects and supports experimental hub modes for replicating data to additional targets, such as ClickHouse or secondary PostgreSQL instances.

Depending on your existing database or application, our experts can provide recommendations regarding the right target technology. Contact us and we’ll answer all your queries.

Absolutely! To make sure you get the best experience from your trial, we’ll need some information about your project. Book a demo with our experts to discuss your migration goals, scope, and direction. This allows us to customize Ispirer Toolkit specifically for your needs.

There is no free access to the IDM license. You can request a demo session through our team. During the session, we will help you figure out how IDM can fit your data migration project.

Conversion quality depends on migration type, direction, and source code features. Nearly 100% of tables and data are converted for most directions. Approximately 75-95% of SQL code can be converted correctly by the tool. When the source code includes mostly business logic, as in the case of COBOL applications, around 70%-90% of the code can be converted automatically. For an application with a GUI, the initial conversion rate can be lower. However, in such cases, the customization of Ispirer Toolkit allows to achieve 90% of conversion.

Ispirer Toolkit works on the basis of thousands of built-in conversion rules. Customization means our experts can adapt these rules to your specific project needs - by creating new ones or fine-tuning existing ones.
This ensures your migration is not only more accurate and reliable but also significantly faster, with fewer manual corrections required. You can decide which improvements are needed on your own or collaborate with our specialists to identify them.
The ultimate goal of customization is to maximize the efficiency of automated migration. With tailored rules, projects often require far less time and effort - sometimes reduced by a factor of ten or more.

If you have your own team of experts with sufficient migration expertise to successfully migrate your database or application, Ispirer Toolkit is the best option for you. It will greatly simplify your team's work and speed up the migration project. If your team lacks the necessary expertise, our migration services will be the right choice.

Yes. Our experts have accumulated extensive experience not only in database and application migration but also in other facets of software modernization and optimization.

For you to be able to evaluate the conversion quality that could be achieved in the potential migration project, we offer a Proof-of-Concept. We will migrate a small piece of your code using Ispirer Toolkit and showcase the result of migration. It would allow you to evaluate the conversion quality at a smaller scale and cost before making a purchase decision.

As part of the services, we work with almost all technologies, even those that are not supported by the Ispirer Toolkit. Feel free to contact our support service, even if you have not found the technology you are interested in.

The price of a migration project depends on your migration direction, code volume, duration, and unique features of your code. To get an estimate of your project, please, contact our support service agents.

IDM achieves exceptional speeds of 250 GB per hour by leveraging Foreign Data Wrappers and parallel multithreading. The tool bypasses middleware bottlenecks, reading data directly from Oracle and writing to PostgreSQL in concurrent batches. This allows you to maximize your hardware's potential, ensuring consistent high performance even for terabytes of data.
The actual speed varies depending on the architecture.

IDM supports the full spectrum of Oracle data types, including complex structures and BLOBs (Binary Large Objects), migrating them at full speed. During the Table Adoption phase, the tool automatically maps columns and handles data type conversions, while also offering you the flexibility to apply custom mappings for non-standard cases.

Yes. You can use IDM in command line mode to streamline your data migration process.
The current IDM workflow also prioritizes ease of use through a comprehensive Graphical User Interface (GUI). This intuitive dashboard allows you to manage projects, configure connections, select tables, and monitor granular progress visuals without needing deep scripting expertise. You control the entire lifecycle — from creation to finalization — directly from this visual environment.

You need zero middleware parameters. IDM is designed as a direct-connection solution. It leverages Foreign Data Wrappers to access Oracle data in read-only mode from the PostgreSQL side. This streamlined architecture eliminates the need for intermediate software, simplifying your setup and enhancing security.
