Switching from Cursor to Claude Code Without Restarting Your Project
The quick answer
You can try Claude Code without starting your project over. Save a clean checkpoint, give it one small task and keep your current setup until you've checked the result.

You can try Claude Code without starting your project over. Save a clean checkpoint, give it one small task and keep your current setup until you've checked the result. The same approach works if you're moving from Claude Code to Cursor.
Before your next renewal, compare the Cursor and Claude Code plan differences as well as the result of this small migration trial.
The same method applies when moving in the opposite direction. A successful migration preserves working behavior while testing whether the new tool improves your next task.
Give the new tool a useful starting point
The hard part is handing over the decisions that matter: which behavior must stay, which command runs the tests and which bug you're fixing now. The new tool doesn't need every old conversation. It needs enough context to work on your project without reopening decisions you've already made.
What to hand over
Before starting the new agent, collect five things:
- The current branch or commit and an explanation of any uncommitted changes.
- The command that starts the application and the checks that normally pass.
- One specific task with an observable acceptance condition.
- Important architectural decisions and files that should remain unchanged.
- Known failures that predate the task.
Keep this packet short enough to inspect. It should tell the new agent how to work safely in the project, not preserve every suggestion ever discussed. A large transcript often contains rejected directions alongside accepted decisions.
Review persistent instructions before carrying them over. Shared facts such as build commands and source-of-truth files belong in project documentation. Client-specific commands or integrations may need a separate note. Do not assume two products interpret every instruction file or skill in the same way.
Check authentication before testing usage
Verify whether the new session uses your subscription or an API key. Anthropic's subscription guide warns that API-key configuration can result in API billing instead of subscription consumption. A trial that accidentally uses another billing route cannot answer whether the subscription is better value. Authentication and plan guidance.
Keep credentials out of the migration packet, repository and screenshots. Confirm the account mode through the tool's status or settings rather than copying secret values into a conversation.
If your concern is the interface, evaluate the Claude Code editor extension as well as the terminal. You may be able to preserve a familiar editor while changing the agent workflow. Official editor integration.
Pick a task that can reveal a difference
Choose a small bug with a reproducible failure or a feature with a clear user-visible result. Avoid starting with a broad redesign, dependency migration or “clean up the whole project” request. Those tasks introduce too many variables to tell whether switching helped.
Ask the new agent to inspect the relevant code and propose a bounded approach before editing. Once it implements the change, inspect the diff, run the acceptance check and confirm that unrelated behavior still works. Record intervention time and any unexpected scope expansion.
If you compare both tools, run them from equivalent starting points. Do not hand the second tool a repository already repaired by the first unless you are intentionally testing review rather than implementation.
Keep rollback straightforward
| What changed | How to preserve a clear comparison |
|---|---|
| Agent-generated code | Isolate it in a branch or checkpoint before integration |
| Local editor settings | Record only the relevant settings you changed |
| Project instructions | Review changes as documentation, not automatic improvements |
| Dependencies | Require a task-specific reason and inspect the lockfile diff |
Do not delete the old setup, cancel a needed work account or rewrite project conventions on the strength of one impressive answer. A short overlap period may be useful if your budget permits it; otherwise compare during sequential billing periods.
Decide from the completed handoff
The new tool has earned a place when it completes representative work, respects boundaries and leaves you able to explain the result. If it fails, first distinguish missing setup from a recurring capability problem. Fixing a missing test command is different from repeatedly accepting incorrect patches.
A good switch leaves you with the same working project and a clearer idea of which tool suits you. If evaluating the new agent starts turning into a rewrite, stop and go back to the small task you chose. Finish that comparison before changing anything else.
