<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📦 &#039;&#039;&#039;Data migration&#039;&#039;&#039; is the process of transferring insurance data — [[Definition:Policy | policy]] records, [[Definition:Claims | claims]] histories, [[Definition:Premium | premium]] transactions, and associated documents — from one system or platform to another, typically during a technology upgrade, carrier acquisition, or transition to a new [[Definition:Policy administration system (PAS) | policy administration system]]. In an industry where decades of legacy records may reside in aging mainframes or flat-file formats, migration projects are among the most complex and consequential IT undertakings an insurer can face.<br /> <br /> 🔄 A successful migration follows a disciplined sequence: data profiling to understand source-system quirks, mapping source fields to the target schema, cleansing and transforming records to meet the new platform&#039;s validation rules, and extensive reconciliation testing before cutover. Insurance-specific complications abound — historical [[Definition:Endorsement | endorsements]] must remain linked to their parent policies, [[Definition:Loss reserve | reserve]] triangles must carry forward intact for [[Definition:Actuarial | actuarial]] analysis, and [[Definition:Regulatory reporting | regulatory reporting]] continuity must be preserved so that filings to bodies like the [[Definition:National Association of Insurance Commissioners (NAIC) | NAIC]] remain uninterrupted. [[Definition:Insurtech | Insurtech]] vendors increasingly offer migration toolkits with pre-built connectors for common legacy platforms, reducing the manual effort that historically made these projects run over budget and behind schedule.<br /> <br /> ⚠️ Botched data migrations carry severe consequences. Incomplete [[Definition:Claims | claims]] records can lead to mismanaged [[Definition:Loss reserve | reserves]], orphaned [[Definition:Policy | policy]] data may leave [[Definition:Policyholder | policyholders]] without proof of coverage, and broken audit trails invite [[Definition:Regulatory action | regulatory penalties]]. Conversely, a well-executed migration is a catalyst for broader [[Definition:Digital transformation | digital transformation]] — once clean, unified data lives in a modern system, carriers unlock capabilities like real-time [[Definition:Underwriting | underwriting]] analytics, automated [[Definition:Bordereaux | bordereaux]] generation, and advanced [[Definition:Fraud detection | fraud detection]] that legacy environments simply could not support.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Policy administration system (PAS)]]<br /> * [[Definition:Data lake]]<br /> * [[Definition:Legacy system]]<br /> * [[Definition:Data quality]]<br /> * [[Definition:Digital transformation]]<br /> * [[Definition:System integration]]<br /> {{Div col end}}</div>
