Transware engineers talk about appeal of the "Caravel™ series" and the future of legacy systems

Migration projects from legacy systems to the cloud often face two main challenges: the first is data consistency. Data formats and protocols used in legacy systems are not always compatible with the latest cloud technologies, so there is a risk of data inconsistencies during migration. In addition, older systems have been in use for decades and have often developed their own specifications, which frequently cause data compatibility and formatting issues during migration to the cloud.

The second is “ensuring overall system reliability. Many projects are highly dependent on legacy systems, and moving a system that has been used and trusted for a long time to the cloud will have a direct impact on operations. Therefore, it is necessary to proceed very carefully. In a situation where system downtime and data inconsistencies are not tolerated, ensuring reliability throughout the project is paramount, as the slightest error can lead to serious problems. Lack of know-how and inadequate documentation due to retiring engineers also play a major role. Risks increase if necessary information is not shared or if the migration process proceeds with incorrect information.

In order to address these challenges, a thorough preliminary investigation is essential. First, we utilize our conversion services to conduct a detailed analysis of the current status of the entire system. We visualize the system structure and dependencies, and clarify unclear specifications and issues. Next, we create clear conversion rules and execute automatic conversion using tools. This enables efficient conversion while minimizing human error. In addition, step by step operational testing is performed to resolve potential problems as early as possible.

Data migration will be done carefully and training will be provided for the new environment.
After the migration, we follow up and provide support until the system is running stably.
Throughout the entire process, we aim to ensure a smooth transition with careful planning to avoid burdening the client's operations.

We place great importance on communication and close collaboration with our clients. We report progress and issues in a timely manner and make adjustments as necessary to ensure that operations are not disrupted during the system migration.

We also place importance on being flexible and responsive to our clients' requests and concerns. In particular, we take great care to ensure that no mistakes are made in the migration of business logic through careful confirmation. To ensure that our clients can proceed with their projects with peace of mind, we also focus on building relationships of trust and providing long-term support.

After the transition, we provide training on how to use the system and any necessary support as needed, and act as a backup until the client is comfortable with the new technology, helping them to implement the new system with confidence.

We often receive words of appreciation from our clients for the smooth transition. In particular, they appreciate the fact that the migration was successful without disrupting their business operations, despite the complex process of migrating from a legacy system. Another factor that gives our clients peace of mind is the fact that our support system continues to function well after the system migration. When clients migrate to a new system, they often have concerns about the reliability and proficiency of the system, and our ongoing support ensures that they can use the new system with confidence.

Even after the migration work was completed, we have received feedback from some of our clients that they feel secure in our immediate response to any problems they may have. We feel that they appreciate not only our technical support, but also our prompt and friendly response. When we receive this kind of feedback, we are able to reaffirm that our work is valuable to our clients, and it is very rewarding.
