Modernise what matters and leave the mess behind.
The new platform is chosen. The real question is what to move. Reperta shows what you have, what depends on what and where the numbers disagree, so you only rebuild what earns its place.
Sound familiar?
Everything goes on the migration list.
Reports survive because nobody has the evidence to argue for retiring them.
The same argument moves with you.
Two revenue definitions do not become one just because both are rebuilt in Power BI.
Switch-off depends on what you cannot see.
Hidden workbook links and manual steps surface after the old platform is gone.
How Reperta helps
- 1
Understand the starting point
Inventory every report, read its logic and map what depends on what.
- 2
Agree the scope
Owners decide what to keep, fix, retire or rebuild, with the evidence in front of them.
- 3
Build on agreed numbers
Carry approved definitions into the migration, prepare the work for review and check the results before cutover.
What depends on what. Every link between reports and sources, with the evidence for each one, so the build order is clear.
Northwind: start with the foundations
Group P&L Consolidation FY26.xlsx was Northwind's one critical asset, with 4 reports depending on it. That made it the first thing to rebuild.
