Ten articles on why migration assessments measure the wrong thing — and what to measure instead. The mathematics is universal. The examples are from SAP. Start anywhere.
Start here: If you read one article, read The 98% Problem. If you want the mathematics, read Bijective Proof. If you want to understand the engine, read Five AI Personas.
Your programme dashboard is green. Your data hasn't been tested. Here's what that means — and why it matters for every system migration, not just SAP.
Every system migration transforms data. Almost none of them prove the transformation is correct. Here is the mathematics that changes that.
A record that loads successfully is not the same as a record that works. In enterprise systems, data has structure — and if you migrate the data without respecting that structure, you get records that reference things that do not exist.
What if the mapping kernel already knew the rules? What if the entire migration assessment ran in fourteen minutes instead of six months?
Mapping coverage is a progress metric, not a safety metric. The five percent you have not examined contains eighty percent of your cutover-weekend failures.
The economics of data migration have not changed in twenty years. The work has. If the assessment is mathematical — not manual — what does that do to the cost equation?
In every other migration tool, failures are bad news. In a proof-based system, failures are the most valuable output — because each one is a diagnosed, remediable, prioritised finding.
Most migration programmes disband the data team within weeks of cutover. The system they built starts decaying the moment they leave. What if the engine that proved your migration could guard your data permanently?
René Thom's catastrophe theory describes how smooth changes produce sudden, discontinuous jumps. It also explains — with mathematical precision — why the standard approach to enterprise migration is structurally fragile.
The industry standard is: load first, check second. What if you reversed the order? What if every record was proven correct before it entered the target system?
