  • Author: Nine Brains Team

Client Overview

A financial services company faced the challenge of migrating its critical applications from an outdated Delphi system to a modern version. The existing system, deeply integrated into daily operations, required a seamless transition to avoid business interruptions.

Challenges

  • A legacy system with outdated dependencies.
  • Risk of business disruption during migration.
  • Limited internal expertise on the latest Delphi version.
  • Need for cost-effective migration while maximizing internal team involvement.

Our Approach

    1. Initial Assessment & Strategy Development:
      • Conducted an in-depth analysis of the existing Delphi system.
      • Identified critical bottlenecks that needed resolution before migration.
      • Developed a phased migration plan to ensure continuity.
    2. Guided Migration Process:
      • Provided expert consulting to assist the client’s team throughout the migration.
      • Trained internal developers to handle portions of the migration independently, reducing consulting costs.
      • Implemented best practices to optimize the system’s performance in the new environment.
    3. Knowledge Transfer & Ongoing Support:
      • Delivered customized training sessions on the latest Delphi version.
      • Ensured smooth adoption with post-migration support and troubleshooting.
      • Helped the team establish best practices for maintaining the new system.

Results

  • Seamless Migration: The transition was so smooth that end-users did not notice any disruption.
  • Time Efficiency: The project was completed ahead of schedule.
  • Cost Reduction: Only 50% of the initially allocated consulting budget was utilized due to a focus on empowering the internal team.
  • Increased In-House Expertise: The client’s developers gained the necessary skills to maintain and optimize the new system without external dependency.
