The real cost of a broken migration
Data quality collapse
Every hour underwriters spend fixing broken migrated data is an hour not spent on new business, renewals, or broker relationships. When your endorsement chains don't reconcile, your underwriters stop trusting the system -- and start keeping their own spreadsheets.
Timeline spiral
What was scoped as six months becomes twelve. Then eighteen. Every delay compounds -- regulatory reporting windows close, broker relationships strain, and the board starts asking whether the migration was worth it.
Broker relationship damage
When your brokers can't get accurate quotes because the migrated data is unreliable, they route business elsewhere. The combined ratio impact of lost business never shows up in the migration project plan -- but it shows up in the P&L.
Plan. Run. Prove.
Insurance Migration Control for every stage of your migration.
Plan
First, we map every policy, every endorsement, every exotic rider in your book. Not just the schema -- the business logic. The retroactive adjustments your current system handles in batch jobs at 2am. The delegated authority agreements that modify coverage mid-term. We build a model of your actual book, not the one in your data dictionary.
Customer sees:
A complete migration blueprint that your underwriters and actuaries can validate.
Run
KeystoneMigrate executes in your environment. Your data never leaves your data platform (Databricks, Snowflake, Fabric, or similar). We process in-situ within your environment -- mapping, validating, reconciling -- with full audit trails. Your team watches it happen. No black box, no 'trust us', no data leaving your perimeter.
Customer sees:
Real-time migration progress with validation checkpoints at every stage.
Prove
Before cutover, we prove it worked. Not a sample -- the full book. Every policy, every endorsement chain, every reserve calculation. Your actuaries get reconciliation reports. Your compliance team gets audit evidence. Your underwriters get clean data they can trust from day one.
Customer sees:
Evidence packs that satisfy your regulator, your board, and your underwriters.
Real migrations. Real experience. Two stories that built KeystoneMigrate.
A troubled 2016-2019 programme migrating 1M+ personal lines showed what was broken in insurance migration tooling. In H2 2025, our first product engagement proved KeystoneMigrate works — delivering a Farm/Ranch/Equine specialty book from a completely undocumented source system in six months.
