Reengineering & Migration

Re-engineering and migration are important permanent processes for organizations that are constantly upgrading themselves to maintain a modern and dynamic business. The reasons are simple. You are always facing difficulties while optimizing the business processes if you have legacy systems. On the other hand, legacy systems drive up maintenance costs. The strategic way is to a build a long term plan that incorporates how to upgrade and grow the IT infrastructure. This plan should involve the projects for legacy systems re-engineering and migration. Smart and predictable re-engineering and migration processes support the growing needs of organizations, without hindering existing business processes.

The challenges

The critical need of the re-engineering or migration process appears when organization faces issues like:

  • Legacy System Management

This process always takes money as you are required to keep a team that provides support and maintenance to your existing system. Keep in mind, that from year to year the skills required for this task become more and more rare which means that you can't grow or reorganize the team in a fast way.

  • Ensuring reliability and Quality Assurance

Technical progress is not staying still. Solutions created years ago are not as controllable and manageable as the more modern ones. There are less tools and technical features in solutions to clearly control their behavior. It becomes a real challenge to effectively manage the "black box".

  • Maintaining business agility

It is not easy to maintain the legacy software solution that supports all changes in business processes. Many times organizations find themselves missing out on opportunities as they are not able to respond fast enough to market demand, which results in lost competitive advantages.
