Code Migration & Modernization
Modernize your codebase with confidence.
Enable large-scale transformation. Identify legacy systems, scope impact, and automate migrations, refactors, and fixes across your entire codebase.
Trusted by the world's largest dev teams
Three gaps that stall modernization initiatives
Modernization efforts stall because of a lack of context and an inability to safely execute changes. These aren't planning failures. They're infrastructure gaps.
One platform
From discovery to execution
Most teams try to close these gaps with separate tools. The problem isn't the tools individually. It's the disconnection between them. Scope errors compound, progress tracking drifts from reality, and execution runs on incomplete context.
Sourcegraph closes all three gaps from the same context layer. The intelligence that scopes the migration is the same intelligence that tracks progress and grounds every agentic action during execution. No handoff between systems. No opportunity for scope to drift.

How teams use Sourcegraph for migration and modernization
Library and dependency upgrades
Find every call to a deprecated dependency and roll out the upgrade with consistent changes across all affected repositories.
API deprecation and migration
Scope the full impact of an outgoing API, then execute replacement changes at scale with visibility into which repos are updated and which aren't.
Framework and language migrations
Sourcegraph scopes multi-repo framework migrations in hours and executes them in days.
Large-scale refactoring
Code Search finds every instance, SCIP confirms the dependency graph, and Agentic Batch Changes executes systematically across every repository.
Security remediations
Find every affected pattern across your entire codebase immediately and confirm complete coverage, not estimates.
Compliance and policy enforcement
Track adoption, identify violations, and remediate at scale with auditable change workflows.
Platform capabilities for code migration
Code Search. Deterministic, exhaustive search across every repository and code host.
Deep Search. AI agent that answers complex questions about scope, dependencies, and architecture.
SCIP Code Intelligence. Symbol-level precision across languages, with accurate go-to-definition, find-references, and dependency resolution.
Agentic Batch Changes. Agent-driven, auditable code change execution across every repository, with human oversight and centralized PR tracking.
Code Insights. Track migration progress and remediation burndown across the organization in real time.
Code Monitoring. Detect regressions and policy violations as the codebase evolves.
