Challenge: I integrated a legacy ERP with a cloud-based CRM, needing to maintain data accuracy and avoid disruptions. Solution: 1. Data Mapping: I started by analyzing and mapping data fields with Sunopsis that I developped (now called ODI) to ensure a smooth migration. 2. Middleware: I used middleware to connect both systems in real-time without altering existing structures. 3. Pilot Testing: A limited rollout to a small team helped identify and fix issues before a full deployment. The result was a seamless integration with minimal disruption. What strategies have you used to tackle similar challenges?

Let me tell you what I learned from a legacy system migration: Don't try to eat the elephant in one bite. When we faced integrating a 15-year-old system with our new cloud platform, we succeeded by treating the old system like a wise but stubborn elder – respect what works, then gradually introduce change. Start with a parallel run strategy. We built adapters and ran both systems side by side, moving one service at a time. Kept our veteran developer close – his tribal knowledge was worth more than any documentation. Map the dependencies before touching anything. Legacy systems aren't technical debt – they're battle-tested business logic waiting to be modernized.

It requires a careful, step by step approach. Thoroughly understand both the legacy system and the new software to identify compatibility issues and gaps. Engage with your team and key stakeholders early, ensuring everyone is on the same page about goals and timelines. Plan for phased integration to minimize disruption, testing each stage before moving forward. It’s also essential to provide training and support for your team to adapt to the new system. By communicating openly, being patient, and focusing on gradual improvements, you can ensure a smoother transition and long term success.

I have participated in the implementation of an enterprise software solution, and the process requires meticulous planning for successful execution. Elite project management skills are essential to ensure oversight of the project from start to finish. Effective communication and anticipated benefits must be disseminated throughout the organization. Subsequently, representatives from each business unit act as champions within their respective departments. These champions will advocate as the project is rolled out in phases. Following the successful implementation, training must be provided to the organization on how to use the new system. This entire process demands tactful skills to secure buy-in and dedication for success.
