Migrating from Legacy ERP to Business Central: Lessons Learned
Migrating from a system is not just about the system; it is about transforming the way your company works. If you are about to embark on the journey to the cloud, here are the hard-earned lessons we learned along the way. 1. “Lift and Shift” is a Trap The biggest mistake companies make is treating the migration as a copy-and-paste operation. They want to take their messy, convoluted processes from the old system and copy them over to Business Central. The Lesson: Don’t automate a bad process. Legacy systems are often messy because the software couldn’t do what the business needed. It required workarounds. Business Central is a much more capable system. Take advantage of the migration to think about your processes. If your old system required five steps to approve a purchase order, see if Business Central can’t do it in two. If you try to make Business Central look and act exactly like your old Legacy system, you will be throwing money away. 2. Data Hygiene is Non-Negotiable Business thought they had clean data. They didn’t. On extracting data from the old system, we usually discover that there were thousands of obsolete customer data, duplicated vendor data, and inventory items that were not sold in the last ten years. The Lesson: Don’t boil the ocean. Don’t migrate everything. You’re moving into a new house. Don’t bring the trash with you. Archive the old data. Keep the old system accessible. Make it read-only. Cleanse the master data. Customers. Vendors. Items (GL accounts). Bring the opening balances. Do bring relevant historical data but not ten years of closed transactional history. 3. Configuration vs. Customization This is the Golden Rule of Business Central. In the old days, we used to customize the code for everything. We wanted the button to be blue, not grey. We wanted the report to be printed in a specific font. The Lesson: Stay Standard (Standard = Good). Every time we customize the code in BC, we make it harder and costlier for future upgrades. Try and configure the system using standard settings. Try and look for App Source extensions/add-ons rather than customizing code. Customize only if it gives you a competitive advantage. 4. The “Excel Trap” is Real One of the most powerful features of Business Central is its native Excel support. However, be warned that it is also one of the most insidious “features.” During the go-live of our project, we had users who were afraid of the new UI. Instead of learning how to enter a sales order in BC, they were trying to download everything into Excel, manipulate it there, and paste it back into the system. The Lesson: Train Early and Train Often Change management is harder than the technical implementation. People need to be convinced that Business Central is easier than their spreadsheet hell. Invest in “Champion Training” find super users in every department who will be able to pressure their co-workers into using the system correctly. 5. Your Partner Matters More Than the Software Business Central is a wonderful product, and it’s a platform. It needs a partner to implement it. Chose a partner based on a bid price, and it was a disaster waiting to happen. Chose the lowest bidder, and they treat like a number. The Lesson: Find a partner that understands your industry, not just the software. A retail implementation versus a manufacturing implementation is vastly different. Changing partners halfway through the project to one that specialized in the industry costs you more. 6. The Go-Live is Not the Finish Line Go Live day is, crossing the starting line at a marathon. The First Month Was a Bumpy Ride Users forgot passwords. Reports looked a little different. Changes needed to posting groups etc. The Lesson Plan for a “Hypercare” period. For the first 4 to 6 weeks after Go Live, be prepared to need extra support. Keep your implementation partner on speed dial. Don’t consider your project complete until you have successfully closed a month-end and run your payroll. The Bottom Line Migrating from a legacy ERP system to Business Central is hard. It takes money, time, and a thick skin. But is it worth it? Yes. You will have a real-time visibility into business. Can close financials in days instead of weeks. Remote workers can access data from anywhere and you don’t have to think about server maintenance anymore. If you are considering making the move from a legacy ERP system to Business Central, take the leap, clean your data, and trust the process for your journey to the cloud.
