Migrate Fly.io app configuration, runtime images, Machine resources, regions, volumes, or Managed Postgres through staged change control.

  • Works in 6 steps: Classify the change surface → Freeze current state and contract → Build a staging rehearsal → …

  • SKILL.md covers Overview, Prerequisites, Instructions and Authentication, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Flyio Upgrade Migration is an agent skill from jeremylongshore/tons-of-skills-marketplace. Migrate Fly.io app configuration, runtime images, Machine resources, regions, volumes, or Managed Postgres through staged change control. Use when upgrading a live workload. Trigger with: "upgrade Fly app", "migrate Fly region", "change Fly runtime safely".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Requires current and target contracts, an immutable backup or export where data is involved, a representative staging boundary, and approved rollback criteria.

It sits in Databases. It works with PostgreSQL. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Upgrading a live workload
  • With: upgrade Fly app
  • Migrate Fly region
  • Change Fly runtime safely

Example prompts

  • “upgrade Fly app”
  • “migrate Fly region”
  • “change Fly runtime safely”
  • “/flyio-upgrade-migration”

Requirements

  • Compatibility (from SKILL.md): Requires current and target contracts, an immutable backup or export where data is involved, a representative staging boundary, and approved rollback criteria.
  • Pre-approved tools (allowed-tools): Read, Grep, Write, Edit

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Classify the change surface
  2. Freeze current state and contract
  3. Build a staging rehearsal
  4. Plan data movement explicitly
  5. Canary the approved change
  6. Complete or reverse

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • fly.io
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires current and target contracts, an immutable backup or export where data is involved, a representative staging boundary, and approved rollback criteria.

    From compatibility in the SKILL.md frontmatter.

Context cost

Flyio Upgrade Migration loads about 1.3k tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 535 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Fly.io Runtime and Platform Change Control

Overview

Replace the obsolete Apps v1-to-v2 tutorial with ongoing change control for the current Machines platform. Treat flyctl, fly.toml, images, architecture, Machine resources, regions, volumes, and Managed Postgres as separate migration surfaces with distinct rollback and data risks.

Prerequisites

  • Current and target versions, configuration, image, architecture, resources, regions, and data topology
  • Provider documentation and release notes retrieved at the change boundary
  • Backup, export, restore test, acceptance gates, owner, approver, and rollback window

Instructions

Step 1: Classify the change surface

Separate CLI behavior, config schema, API contract, image or runtime, CPU architecture, VM size, region placement, volume state, and Managed Postgres changes.

Step 2: Freeze current state and contract

Record flyctl version, image, Machine instance versions, configuration hash, health, regions, volumes and snapshots, database plan and version, and dependency compatibility.

Step 3: Build a staging rehearsal

Use production-like configuration with synthetic or protected copied data. Exercise application startup, release command, health, connectivity, schema compatibility, and restore.

Step 4: Plan data movement explicitly

For a region-bound volume, create and verify the supported copy or snapshot path before Machine movement. For Managed Postgres, follow its current service features and support path; do not apply unmanaged Postgres commands.

Step 5: Canary the approved change

Change one process group, Machine, or non-production database boundary first. Observe health, errors, latency, data counts, and dependent services for the agreed window.

Step 6: Complete or reverse

Roll through remaining resources only after acceptance. Reconcile every image, instance version, region, volume attachment, and data count; retain rollback assets until expiry.

Authentication

Use a scoped deploy identity for app or Machine changes and a separate least-privilege database identity for data verification. Upgrade work does not authorize exposing snapshots, connection strings, or customer data to local or unapproved systems.

Tool Discipline

Use Read and Grep to inspect application configuration, deployment evidence, provider documentation, fixtures, logs, schemas, and existing tests before proposing a change. Use Write or Edit only for an approved plan, configuration, implementation, test, or redacted receipt. Do not create, deploy, scale, restart, stop, suspend, destroy, rotate, revoke, expose, or migrate live Fly.io resources without explicit operator approval.

Output

  • Current-to-target contract and compatibility matrix
  • Staging, backup, restore, canary, rollout, reconciliation, and rollback plan
  • Migration receipt with resource versions, data evidence, exceptions, and rollback-asset expiry

Return the target organization, app, environment, region set, Machine or database identifiers, source-contract fingerprint, evidence, unresolved risks, rollback state, and final decision without exposing tokens, secrets, connection strings, or customer data.

Examples

An app moves to a new runtime image and VM size. The operator pins current and target images, rehearses startup and release commands, updates one stateless Machine, observes health and latency, then rolls forward. A separate volume move uses a verified snapshot and restore path.

Error Handling

FailureResponse
Provider contract changed during migrationPause, refresh documentation and client schemas, and reapprove the plan.
Canary is incompatible with attached storageUse rolling or a data-specific migration path; do not force the strategy.
Data reconciliation differsStop writes or rollout as planned, preserve both sides, and restore or reverse before the rollback window closes.
