Plan and execute safe cross-system migrations, including service extraction from monoliths. Use when moving data, schemas, interfaces, infrastructure, or service ownership through compatibility windows, dual-running, reconciliation, cutover, recovery, or deprecation. Do not use for deciding whether decomposition is justified, designing a target architecture, or implementing one named technology; route those to the relevant architecture or specialist skill.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Migration Engineering Plan and execute safe migrations across system boundaries. A migration is any change that moves data, schemas, interfaces, infrastructure, or services from a current state to a target state while preserving correctness, availability, and recoverability during the transition. This skill owns the **cross-system migration method** — compatibility design, staging, reconciliation, cutover, recovery, and deprecation. It does not own the implementation details of any single technology or subsystem; those belong to specialist skills. ## When to use Load this skill when the task involves: | Trigger | Example | |---|---| | A schema change that must not break existing readers or writers | "Add a non-nullable column to a high-traffic table with zero downtime" | | A data migration between stores or representations | "Migrate user profiles from Postgres to a dedicated service with its own database" | | An API version migration with a deprecation window | "Move consumers from v1 REST to v2 GraphQL over six months" | | An infrastructure or service migration | "Shift a workload from self-hosted VMs to a managed platform across regions" | …

How to install
mdr add magnus919/agent-skills/migration-engineering@sha256:6cbc9cda44a5fc3cThe line at the top of this page pins the label git:20260823.18f78a1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
