Migration Service

Move everything from the old system to the new one with parity verified, nothing lost, and a rollback ready.

What it adds

The builder studies your inventory exports, past migration runbooks, and validation checklists to construct an offer centered on a safe transition between systems, with a documented parity test and a cutover plan. It converts by addressing the single fear that stalls every migration — losing data or breaking operations during the switch — and answering it with a verification mechanism rather than reassurance.

What your builder is told to do

8

The actual instructions, in order.
  1. 1

    Inspect the system inventory and past migration runbooks in the source files, and enumerate the categories of things that must move: data, configuration, integrations, permissions, automations, and historical records.

  2. 2

    State the promise in terms of parity and continuity: everything in the inventory arrives in the new system and is verified, with operations uninterrupted during the switch.

  3. 3

    Publish the migration phases — inventory, mapping, trial migration, validation, cutover, and post-cutover monitoring — and name the artifact produced by each phase.

  4. 4

    Make the parity test the centerpiece: describe the checklist that compares old versus new, who signs off on it, and the rule that cutover does not proceed until it passes.

  5. 5

    Define the rollback plan concretely — what triggers it, how long it takes, and what state the buyer is returned to — because the existence of a rollback is what makes the buyer willing to schedule a cutover date.

  6. 6

    State the buyer's responsibilities: access to both systems, availability of someone who knows the legacy system's quirks, a freeze window, and sign-off authority.

  7. 7

    Apply responsive rules: on mobile show phases as a vertical progress list with the parity checklist in a full-screen expandable view and a sticky cutover-planning action; on tablet show phases and parity categories in two columns; on desktop render a horizontal phase timeline above a side-by-side old-system / new-system mapping table.

  8. 8

    End with one action — schedule a migration assessment — and describe what the assessment produces and how long it takes.

Edge cases it handles

5

The things an agent skips when you only say "build a migration service".
  • The legacy system holds undocumented behavior nobody remembers — define the discovery phase and how newly found items affect scope and timeline.
  • Data quality in the source system is poor — state whether cleanup is included, excluded, or quoted separately.
  • The two systems have no equivalent for a given feature — define the gap-documentation and decision process rather than promising exact parity.
  • The buyer cannot tolerate a freeze window — describe the phased or dual-write approach and how it changes effort.
  • Licensing or access to the legacy system expires mid-project — flag it as a prerequisite dependency with a stated date requirement.

Definition of done

7

Your builder is required to check every one of these before reporting the work finished.
  • An inventory of every category that must move is published on the page.
  • The parity checklist and its sign-off rule are presented as the gate before cutover.
  • A rollback plan with trigger conditions and duration is stated.
  • Buyer responsibilities including freeze window and legacy-system knowledge are listed.
  • Gaps with no equivalent are addressed by a documented process rather than a parity promise.
  • Mobile progress list, tablet two-column, and desktop timeline-plus-mapping layouts all behave as specified.
  • The builder reports which source files it used to build the inventory and phases, and lists every migration assumption left unresolved.

How it works

  1. 1

    Copy the link

    Grab the Markdown blueprint URL for this offer type.

  2. 2

    Give it to your builder

    Paste it into Claude Code, Cursor, Codex, or whatever AI builder is already working in your app.

  3. 3

    It maps, then builds

    Your agent reads the blueprint first, then builds the offer into your app around the product, audience, and stack.

Works with your stack

These blueprints are written to adapt. They tell the agent to detect your framework, match your existing design system, and use your source files instead of guessing the offer.

Need it tighter than that? Customize the offer file and tell it exactly which source docs and stack to use.
