Map code and service impact
Automatically discover dependencies across repositories and runtimes.
Coordinate migration waves
Plan, sequence, and track waves with clear ownership and timing.
Verify production cutovers
Run pre-cutover checks and monitor health to cut over with confidence.
One connected migration record
The target version is only one part of the system.
CutoverGrid turns repository state, dependencies, infrastructure, delivery workflows, team ownership, and production safeguards into one continuously updated plan.
Explore the productApplications, shared packages, infrastructure, and delivery configuration.
Each connected to a commit, rule, file, affected service, and owner.
Sequenced by shared dependency, operational risk, and rollback boundary.
Build, test, performance, monitoring, rollback, and approval conditions.

What We Do
One operating model from repository discovery to verified cutover.
Every stage adds evidence, ownership, or control to the same migration record.
Discover
Connect repositories and create reproducible commit-pinned snapshots.
Inventory
Identify runtimes, frameworks, packages, tooling, and environments.
Map
Reveal cross-repository dependencies, services, owners, and data paths.
Assess
Detect compatibility blockers, missing safeguards, and unknowns.
Estimate
Model effort as a range with assumptions and calibrated confidence.
Plan
Compare strategies and turn findings into sequenced technical work.
Coordinate
Assign owners, dependencies, acceptance criteria, and rollback steps.
Verify
Evaluate engineering and operational gates before production cutover.
Learn
Compare predicted and actual outcomes to strengthen the next migration.
Evidence-backed assessment
Open full report
Every recommendation stays connected to its source.
Move from executive readiness to file-level evidence without leaving the migration record.

Advancing intelligence across the full modernization lifecycle.
Explore all active initiativesExpanding the official Migration Pack catalog
Maintaining deeper rules for runtime, framework, database, delivery, and platform transitions.
Deepening ownership intelligence
Connecting shared packages and cross-repository blockers to the teams that can resolve them.
Synchronizing engineering workflows
Keeping GitHub, Jira, and Linear work aligned with live migration evidence.
Extending customer-controlled analysis
Increasing private deployment, retention, and isolated worker controls.
Connecting patches to validation
Grounding assisted code changes in deterministic checks and human review.
Building modernization governance
Giving leaders one portfolio view across deadlines, risk, effort, and team capacity.
