# Migrate to Confidence

> Migrate feature flags and experiments from PostHog, Eppo, Statsig, or Optimizely to Confidence using AI-powered migration kits.

The [Confidence plugin for AI coding assistants](https://github.com/spotify/confidence-ai-plugins) includes migration kits that automate moving from PostHog, Eppo, Statsig, or Optimizely to Confidence. Each kit guides your AI assistant through recreating your flags in Confidence and rewriting your application code to use the Confidence SDK. Install the kits and pick the one for your platform:

```bash theme={null}
npx skills add spotify/confidence-ai-plugins
```

The installer works with Claude Code, Cursor, Codex, Gemini CLI, and other AI assistants, and asks which skills and assistant to install to. To get the full plugin—including flag management and documentation search—install it with your assistant's own plugin manager instead.

The plugin works with [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [Cursor](https://www.cursor.com/), [Codex](https://developers.openai.com/codex/), and [Gemini CLI](https://github.com/google-gemini/gemini-cli).

## How Migration Works

Every migration kit runs in two phases:

1. **Flag definitions**: The kit reads your flags, targeting rules, and rollout percentages from the source platform and recreates them in Confidence.
2. **Code transformation**: The kit rewrites your application code from the source platform's SDK to [OpenFeature](https://openfeature.dev/) with the Confidence SDK, creating one pull request per flag.

Each phase separates planning from execution. The kit first writes a plan file that you review, then executes it:

* `plan flag` generates a migration plan for your flag definitions
* `plan code` generates a migration plan for your code changes
* `execute <plan-file>` carries out the plan you generated

Plan files are self-contained and resumable. You can pause a migration, review what remains, and continue later—even with a different AI assistant.

## Before You Begin

To run any migration kit, you need:

* A [Confidence](https://app.confidence.spotify.com) account with a client to resolve flags
* The Confidence Flags MCP server, authenticated with your account—see the [Use AI with Confidence](/docs/quickstarts/use-mcp) quickstart
* The Confidence Documentation MCP server, used during code transformation
* Read access to your source platform, typically an API key—see each migration kit page for details

Some advanced features, such as partial traffic allocation and reusable segments, require a Confidence REST API token in addition to the MCP server. The kit tells you when this applies.
