↝ session-migrate
Carry the conversation forward.
Move local coding-agent sessions between Claude Code, Codex, Pi, OpenCode, and GitHub Copilot CLI.
Install
uv tool install session-migrate
No uv? Use the standalone installer:
curl -LsSf https://raw.githubusercontent.com/xhluca/session-migrate/main/install.sh | sh
pipx install session-migrate works too. Python 3.11+ and Linux are currently
supported. The full command is session-migrate; smigrate is the shorthand.
Quick start
Inspect any native transcript without printing its conversation:
smigrate inspect ~/.claude/projects/-work/SESSION.jsonl
Move a Claude session into Codex and resume it from the same project directory:
smigrate transfer SESSION_UUID --from claude --to codex --cwd "$PWD"
codex resume NEW_SESSION_UUID
Or find an older session by title first:
smigrate catalog refresh
smigrate catalog search "authentication refactor"
smigrate transfer --catalog-id RESULT_ID --to pi
Compatibility
| Source ↓ / Target → | Claude | Codex | Pi | OpenCode | Copilot |
|---|---|---|---|---|---|
| Claude Code | — | ✓ | ✓ | ✓ | ✓ |
| Codex | ✓ | — | ✓ | ✓ | ✓ |
| Pi | ✓ | ✓ | — | ✓ | ✓ |
Claude, Codex, and Pi are sources and targets. OpenCode and Copilot are currently target-only. Same-format migration is intentionally rejected. Antigravity and Cursor remain fail-closed until they expose supported transcript import APIs.
What survives
- User and assistant messages, in order
- Tool calls and their linked results
- Supported inline images
- Portable compaction summaries
- Native session identity, discovery, and resume metadata
Anything target-specific is counted in a content-free migration manifest. The source session is never modified.
How it works
native session → validated event timeline → native target → resume
Each reader projects a versioned native transcript into a small ordered model. Each writer then emits only structures verified against the target CLI. This is session migration, not text export: the target receives a discoverable, resumable native session.

See the development guide before changing a native adapter. New formats need sanitized fixtures and a real native-resume oracle.
