Migration Packs

Versioned migration intelligence for defined technical transitions.

Each pack combines deterministic rules, evidence requirements, execution guidance, and cutover checks for a specific source-to-target change.

Pack architecture

Rules, evidence, and execution guidance move together.

A Migration Pack defines how CutoverGrid recognizes the current state, evaluates compatibility, structures remediation, and verifies the target state.

01

ApplicabilitySource versions, target requirements, and stack conditions

02

AnalysisCompatibility, removed APIs, dependencies, and configuration

03

ExecutionTasks, sequencing, validation, rollout, and rollback

04

MaintenanceVersion history, rule updates, and references

Inside every pack

Technical scope that reaches beyond application code.

Detection

Source versions, target requirements, configuration patterns, manifests, lockfiles, and execution environments.

Compatibility

Dependency constraints, removed behavior, native integrations, framework interactions, and manual-review conditions.

Delivery

Required tests, infrastructure checks, rollout guidance, ownership, approvals, and observability thresholds.

Recovery

Rollback images, data safeguards, traffic controls, decision points, recovery evidence, and post-cutover checks.

Choose the transition

Run a migration-specific readiness assessment.

Select the repositories, target technology, and target version. CutoverGrid applies the right evidence model from the first scan.
