REASON03Keep Your Business Moving - Even During Migration!
Migration projects with Caravel™ are typically one-half to one-third of the cost of a typical project. With the exception of testing, the majority of the project is an automated process, from data migration to security, which significantly reduces the total project cost and manpower workload. This reduces the total project cost and human workload, allowing management resources to be invested in more strategic areas.

REASON04Whatever the Platform, We’ve Got It Handled!
Caravel™ supports a wide range of languages, including common COBOL languages (various types) and RPG, as well as JCL, CL, Assembler, PL/I, and other languages that were difficult to migrate with general migration services. This makes it possible to plan modernization by meaningful units such as business areas, rather than by language. In addition, by using Insight (a visualization analysis tool), the time required to extract meaningful units such as business areas and analyze the relationships between each module is drastically reduced.

REASON05Tons of Success Stories, and Counting!
Caravel™ has been in operation for 350 companies worldwide, mainly financial institutions, over a period of about 30 years, and 12 companies in Japan since 2018, giving us the experience and track record to safely promote projects. We have also been selected as a tool for migration in the double-byte area by Google Inc.

REASON05Flexible Migration Options to Choose From
Caravel™ allows you to choose between two conversion methods, Converter and Express, depending on your goals and budget, provided that the critical business logic is maintained.
With Converter, the converted Java code is in a form that is easy to understand for the average Java engineer. You can also freely choose the Java and JavaScript frameworks and database frameworks, such as Spring Boot, Angular, and MyBatis. Furthermore, the conversion engine is highly customizable, allowing you to freely configure the directory structure, package structure, naming conventions, types/variables, etc., and have them reflected in the engine. By using this engine, coding quality can be guaranteed and receive a rank A rating on SonarQube.
This makes future maintenance work easier for the average Java engineer.
With Express, the converted Java code is converted in a manner similar to common legacy languages, making it more compatible with existing systems; Express allows projects to be completed in a shorter turnaround time and at a lower cost compared to Converter. It is also very close to the operability of the current system, maintaining the feel of a 3270 or 5250 emulator.
This makes it an ideal choice for those who want to keep their budgets low and for current maintenance personnel who intend to continue to maintain the system as it is.
