Make the Process of Legacy System Migration Smooth

Transforming outdated systems is key for business survival and success. Regardless of the nature of a system transformation, the process will require intelligent decision-making and a solid strategy.

Learn tips and tricks on how to take your legacy software to a new level of security and efficiency.

Why opt for legacy system migration?

If you’re still not sure about the changes, here’s the gist: maintaining legacy systems demands large sums of money, increases cybersecurity risks, and decreases performance. Perhaps more importantly, if you continue using legacy software, you might be robbing your company of the chance to keep up with the latest software and make the most of the opportunities it presents. In addition, keeping outdated or obsolete applications might lead to breaching regulations.

If only some components of your legacy software create difficulties, your company may not need to initiate a full transformation. While migration  means adopting a new system, modernization allows you to upgrade the existing one.

CTO’s role

To avoid the pitfalls and maximize the results, the CTO needs to think through the preparation stage:

  • Develop an effective strategy
  • Estimate infrastructural limitations
  • Assess the system’s availability and reliability
  • Check software design for limitations
  • Verify if third-party components are compatible with the system
  • Make sure applications and data are safe
  • Set measures against security breaches
  • Make sure the company abides by the regulations throughout the process
  • Decide what’s plan B
