Challenge

In our migration projects, we focus not only on the technical aspects but also work closely with our clients from planning to execution. This collaborative approach ensures that each project is aligned with the client’s unique needs and business objectives, maximizing return on investment.

Oracle database migration projects often present a range of challenges. One of the most significant is managing compatibility issues, especially when migrating older applications to new environments. We address these challenges through detailed analysis and testing, developing custom solutions when necessary.

Another major challenge is the migration of legacy applications without vendor support. In these cases, we apply reverse engineering techniques and work closely with the client’s IT team to preserve functionality. Handling differences in operating system platforms requires deep knowledge of all the systems involved—expertise that is backed by our decades of experience.
