Here’s Mistake #3 in our 7-part series on BI migration traps:
Throwing away your existing business logic.
Too many migrations start with a blank sheet: “Let’s rebuild everything in the new tool.”
Sounds neat. Feels modern. But here’s what happens:
- Years of hard-earned business rules vanish overnight.
- Sales, Finance, and Ops no longer see the same numbers.
- Endless debates about “what’s the right figure?” restart from zero.
- Adoption collapses, because nobody trusts the reports.
Your business logic is the DNA of your reporting. It’s the shared definitions, rules, and calculations that people rely on every day. Strip that out, and you don’t just lose formulas. You lose trust.
The smarter path?
- Audit what you have today.
- Separate the valuable logic (the rules worth keeping) from the clutter.
- Carry it forward into the new BI model. Then enhance it.
- Document it clearly so everyone knows “this is how we measure success.”
This way, migration becomes an upgrade, not an amnesia event. You preserve institutional memory, while still building cleaner, AI-ready models for the future.
