Complete migration operating model

Connect every technical finding to an executable migration decision.

CutoverGrid discovers the current state, maps impact, identifies blockers, sequences engineering work, and verifies production readiness.

Nine connected capabilities

One system for the full modernization lifecycle.

Each capability produces structured evidence for the next, keeping technical context intact from first scan through production verification.

Discover

Discover the repository landscape

Analyze repositories, branches, workspaces, manifests, lockfiles, CI, containers, infrastructure, tests, and ownership.

Repository landscape discovered across repositories, workspaces, pipelines, and ownership — Repository discovery makes the full technical estate visible before planning starts.

Inventory

Inventory the technology stack

Identify runtimes, frameworks, dependencies, internal packages, build tools, deployment targets, and version relationships.

A structured inventory of runtimes, frameworks, packages, tools, and deployment targets — Technology inventory preserves both component identity and the version relationships between them.

Map

Map architecture and impact

Connect repositories, services, packages, databases, queues, pipelines, infrastructure, environments, and owning teams.

A physical topology map connecting repositories, services, data, environments, and owners — Impact mapping connects every proposed change to the systems and teams it can affect.

Assess

Assess compatibility and risk

Detect blockers, deprecated APIs, removed behavior, native-module risk, version conflicts, legacy runtime pins, and missing validation.

A compatibility scanner detecting safe components and migration blockers — Compatibility assessment separates verified support from deprecated behavior, conflicts, and native risk.

Estimate

Estimate effort with confidence

Provide engineering-day ranges with assumptions, exclusions, confidence, and the unknowns that can change the estimate.

Evidence inputs producing a bounded engineering effort range — Effort ranges remain useful because their assumptions and uncertainty are visible.

Plan

Compare migration strategies

Compare phased migration, coordinated cutover, dual runtime, compatibility layers, canary rollout, blue-green rollout, and other relevant approaches.

Multiple migration strategies connecting the same source and target platforms — Strategy comparison makes risk, duration, reversibility, and coordination tradeoffs explicit.

Coordinate

Build migration waves

Convert findings into sequenced tasks, dependencies, owners, acceptance criteria, validation steps, and rollback conditions.

Service modules sequenced into migration waves with validation gates and ownership handoffs — Waves turn findings into coordinated units of execution with clear entry and exit conditions.

Verify

Verify production cutover

Evaluate builds, tests, performance, error rates, monitoring, infrastructure, rollback readiness, and approvals.

Production traffic passing through verification gates under operational control — Cutover verification combines build, test, performance, monitoring, rollback, and approval evidence.

Learn

Learn from completed migrations

Compare estimated and actual effort, predicted and observed blockers, expected and real risk, and designed versus actual sequence.

A feedback loop turning completed migration outcomes into calibrated rules — Completed migrations refine future estimates, risk models, sequences, and validation guidance.

A shared source of truth

Every role sees the decision context it needs.

Engineering leadership

See readiness, effort, risk concentration, team constraints, and cutover confidence across the migration portfolio.

Platform teams

Trace compatibility evidence, cross-repository dependencies, shared blockers, migration sequence, and infrastructure gates.

Service owners

Receive scoped work with evidence, prerequisites, acceptance criteria, validation steps, and rollback conditions.

Start with the evidence

Build a migration plan your teams can execute.

Connect repositories, identify technical dependencies, and coordinate every wave through verified cutover.
