Moving from Cursor to GitHub Copilot—or back: migration checklist

Switching editors or assistants is rarely about “better AI” and more about how your team ships code. This checklist walks you through a Cursor to GitHub Copilot migration (or a move back) with minimal disruption: repository rules, instructions, skills, MCP-style configuration, editor setup, privacy controls, usage baselines, and a reversible one‑week pilot. You’ll end with a concrete renewal decision based on your workflow—not hype.

Quick decision framework (choose your default, then validate)

Use this to pick a starting point before you pilot.

Start with Cursor Pro if…

• Your team prefers an AI-first editor where multi-file and agentic workflows are central to daily work.
• You want a single environment where “edit + chat + agent changes” feels cohesive.
• You’re standardizing on one editor for most contributors.

Start with GitHub Copilot Pro if…

• Your team works across multiple IDEs and wants a consistent assistant experience.
• You want GitHub-native touchpoints (review flows and CLI-style capabilities) alongside IDE help.
• You already rely heavily on GitHub workflows and want the assistant to follow you there.

Cost baseline (verify before you commit)

As of 2026-07-12, Cursor Pro is $20/month and GitHub Copilot Pro is $10/month. Treat these as dated baselines and confirm current pricing on vendor pages: Cursor — pricing and GitHub — Copilot plans. Also note that usage beyond included limits/credits can change total cost, so your pilot should measure real usage patterns, not just sticker price.

Pre-migration inventory (30–60 minutes)

Before changing anything, capture what “good” looks like.

• Repos in scope: list the 1–3 repositories you’ll use for the pilot.
• Work types: bugfixes, refactors, new endpoints, tests, docs, infra changes.
• Risk boundaries: what changes require human review, what can be agent-assisted, what is off-limits.
• Success criteria: fewer context switches, faster PR iteration, easier onboarding, fewer “AI broke the build” moments (avoid promising productivity gains; just define observable signals).
• Rollback plan: ensure you can revert editor/tooling without blocking merges.

If you want a neutral side-by-side starting point, use the main CTA: the StackTrim comparison audit (helpful because costs and usage assumptions remain editable as your team learns what it actually consumes).

Repository rules: make the assistant safe by default

Most teams get better outcomes from clear repo-level guardrails than from “better prompts.”

H3: Add or tighten contribution and review rules

• Require PRs for non-trivial changes.
• Define “no-go” areas (auth, billing, encryption, migrations) that always need senior review.
• Require tests for bugfixes and behavior changes.
• Document formatting/linting expectations so the assistant can comply.

H3: Create an “AI-assisted change policy” file

Add a short policy doc in the repo (e.g., docs/ai-policy.md) covering:

• What the assistant may do (draft code, propose tests, explain diffs).
• What it must not do (introduce secrets, bypass security checks, change licensing headers).
• How to cite assumptions (e.g., “If you don’t see X in the repo, ask before adding.”)

H3: Standardize a PR template for AI-involved work

Include checkboxes like:

• “I reviewed all generated code.”
• “I ran tests / lint.”
• “I confirmed no secrets were added.”
• “I validated behavior against acceptance criteria.”

Instructions: port what matters, not everything

Both tools support custom instructions and “how we build here” guidance. Don’t migrate a giant prompt blob; migrate the parts that reduce rework.

• Project context: architecture, key folders, naming conventions.
• Definition of done: tests, docs, changelog, error handling patterns.
• Style rules: TypeScript strictness, Python typing, API patterns, logging.
• Preferred libraries: what to use and what to avoid.

Tip: keep instructions versioned in the repo (so they’re reviewable) and reference them from your tool’s instruction system.

Skills and workflows: map tasks to the right interaction mode

Both Cursor Pro and GitHub Copilot Pro cover completion, chat, agentic changes, model choice, and MCP-style workflows. The migration question is: where does each fit in your day-to-day?

H3: Completion-first tasks

• Small edits, renames, boilerplate, tests scaffolding.
• Best practice: keep diffs small and run formatters automatically.

H3: Chat-first tasks

• “Explain this module,” “Find edge cases,” “Propose test cases,” “Draft migration plan.”
• Best practice: ask for a plan first, then code, then tests.

H3: Agentic/multi-file tasks

• Refactors across multiple files, consistent API changes, updating call sites.
• Best practice: require a proposed change list before applying edits; review file-by-file.

MCP-style configuration: keep it minimal and auditable

Both tools can participate in MCP-style workflows (connecting the assistant to structured tools/data sources). Treat this like adding a new dependency.

• Start with read-only or low-risk capabilities where possible.
• Use separate credentials with least privilege.
• Log what the assistant can access (and where those settings live).
• Prefer repo-local configs that can be code-reviewed over per-user hidden settings.

If your team doesn’t already have a tool-connection policy, add one: what’s allowed, who approves it, and how to rotate keys.

Editor setup: standardize the “minimum viable environment”

Avoid a migration that quietly changes formatting, linting, or test behavior.

• Pin toolchain versions (Node/Python/Go, package manager).
• Ensure formatters and linters run the same way locally and in CI.
• Document “one command to run tests” for the pilot repos.
• Confirm everyone can reproduce the same results across IDEs.

If you’re comparing options across your broader stack, keep a short list of alternatives handy via Coding tools and your internal standards.

Privacy controls: decide what’s allowed before the pilot

Don’t assume defaults match your risk tolerance.

• Define what code can be used in prompts (entire files vs. snippets).
• Decide whether sensitive repos are in scope.
• Set rules for secrets handling (never paste tokens; use placeholders).
• Confirm how you’ll handle customer data, logs, and incident artifacts.

Make this a written policy so individual developers aren’t forced to guess.

Usage baselines: measure what you’ll actually pay for

Because usage beyond included limits/credits can change total cost, track:

• How often developers use chat vs. completion vs. agentic changes.
• Which repos trigger the most usage.
• Where the assistant causes rework (failed builds, incorrect assumptions).
• Time spent reviewing AI-generated diffs (a real cost even if subscription is cheap).

Keep this lightweight: a shared doc plus a weekly 15-minute check-in is enough.

The reversible one-week pilot (day-by-day)

Design the pilot so you can switch back without drama.

Day 0: Freeze the variables

• Choose 1–3 repos and 2–6 developers.
• Lock formatting/lint/test commands.
• Write down baseline expectations and risks.

Days 1–2: “Shadow mode”

• Use the new tool for suggestions and plans, but keep changes small.
• Compare how often you need to restate context.
• Capture friction points (setup, prompts, review flow).

Days 3–4: “Real work, guarded”

• Allow multi-file/agentic changes only behind PRs.
• Require tests for any behavior change.
• Track review time and rollback frequency.

Day 5: “Stress the workflow”

• Attempt one refactor or cross-cutting change.
• Validate how well instructions and repo rules hold up.

Day 6: “Cost and policy review”

• Review usage patterns and any privacy/policy issues.
• Decide what to tighten (instructions, MCP access, PR rules).

Day 7: “Switch-back drill”

• Have at least one developer revert to the previous tool for a task.
• Confirm nothing in the repo depends on the pilot tool to proceed.

Safe cancellation or migration checklist (do this before renewing)

Use this whether you’re moving from Cursor to Copilot, Copilot to Cursor, or keeping both.

• Export or copy any custom instructions you want to keep (prefer repo-stored docs).
• Remove tool-specific tasks from your definition of done (keep CI authoritative).
• Audit MCP-style connections: revoke unused keys, rotate any shared credentials.
• Confirm no secrets or customer data were stored in prompts, notes, or scratch files.
• Update onboarding docs: “supported editors,” “how to run,” “how to ask the assistant.”
• Ensure PR templates and AI policy docs are merged and enforced.
• Set a calendar reminder 2–3 days before renewal to review usage and cost.

For internal reference, you can also link the tool page you’re standardizing on (e.g., Cursor profile) in your onboarding docs.

Renewal decision (make it explicit)

At the end of your Cursor to GitHub Copilot migration pilot week, choose one of these and schedule the next review:

1. Renew GitHub Copilot Pro (and cancel Cursor Pro) if your team benefits most from consistent assistance across IDEs plus GitHub-native workflows, and your repo rules/instructions kept multi-file changes safe.
2. Renew Cursor Pro (and cancel Copilot Pro) if your team’s day-to-day relies on an AI-first editor feel and multi-file/agentic editing is smoother with fewer context resets.
3. Keep both for 30 more days only if you can name two distinct workflows (e.g., one IDE-heavy, one editor-standardized) and you’ve set a hard date to consolidate after verifying current pricing and real usage costs.
