+summary: "Move (migrate) a Clawdbot install from one machine to another"
+read_when:
+  - You are moving Clawdbot to a new laptop/server
+  - You want to preserve sessions, auth, and channel logins (WhatsApp, etc.)
+---
+# Migrating Clawdbot to a new machine
+
+This guide migrates a Clawdbot Gateway from one machine to another **without redoing onboarding**.
+
+The migration is simple conceptually:
+
+- Copy the **state directory** (`$CLAWDBOT_STATE_DIR`, default: `~/.clawdbot/`) — this includes config, auth, sessions, and channel state.
+- Copy your **workspace** (`~/clawd/` by default) — this includes your agent files (memory, prompts, etc.).
+
+But there are common footguns around **profiles**, **permissions**, and **partial copies**.
+
+## Before you start (what you are migrating)
+
+### 1) Identify your state directory
+
+Most installs use the default:
+
+- **State dir:** `~/.clawdbot/`
+
+But it may be different if you use:
+
+- `--profile <name>` (often becomes `~/.clawdbot-<profile>/`)
+- `CLAWDBOT_STATE_DIR=/some/path`
+
+If you’re not sure, run on the **old** machine:
+
+```bash
+clawdbot status
+```
+
+Look for mentions of `CLAWDBOT_STATE_DIR` / profile in the output. If you run multiple gateways, repeat for each profile.
+
+### 2) Identify your workspace
+
+Common defaults:
+
+- `~/clawd/` (recommended workspace)
+- a custom folder you created
+
+Your workspace is where files like `MEMORY.md`, `USER.md`, and `memory/*.md` live.
+
+### 3) Understand what you will preserve
+
+If you copy **both** the state dir and workspace, you keep:
+
+- Gateway configuration (`clawdbot.json`)
+- Auth profiles / API keys / OAuth tokens
+- Session history + agent state
+- Channel state (e.g. WhatsApp login/session)
+- Your workspace files (memory, skills notes, etc.)
+
+If you copy **only** the workspace (e.g., via Git), you do **not** preserve:
+
+- sessions
+- credentials
+- channel logins
+
+Those live under `$CLAWDBOT_STATE_DIR`.
+
+## Migration steps (recommended)
+
+### Step 0 — Make a backup (old machine)
+
+On the **old** machine, stop the gateway first so files aren’t changing mid-copy:
+
+```bash
+clawdbot gateway stop
+```
+
+(Optional but recommended) archive the state dir and workspace:
+
+```bash
+# Adjust paths if you use a profile or custom locations
+cd ~
+tar -czf clawdbot-state.tgz .clawdbot
+
+tar -czf clawd-workspace.tgz clawd
+```
+
+If you have multiple profiles/state dirs (e.g. `~/.clawdbot-main`, `~/.clawdbot-work`), archive each.
+
+### Step 1 — Install Clawdbot on the new machine
+
+On the **new** machine, install the CLI (and Node if needed):
+
+- See: [Install](/install)
+
+At this stage, it’s OK if onboarding creates a fresh `~/.clawdbot/` — you will overwrite it in the next step.
+
+### Step 2 — Copy the state dir + workspace to the new machine
+
+Copy **both**:
+
+- `$CLAWDBOT_STATE_DIR` (default `~/.clawdbot/`)
+- your workspace (default `~/clawd/`)
+
+Common approaches:
+
+- `scp` the tarballs and extract
+- `rsync -a` over SSH
+- external drive
+
+After copying, ensure:
+
+- Hidden directories were included (e.g. `.clawdbot/`)
+- File ownership is correct for the user running the gateway
+
+### Step 3 — Run Doctor (migrations + service repair)
+
+On the **new** machine:
+
+```bash
+clawdbot doctor
+```
+
+Doctor is the “safe boring” command. It repairs services, applies config migrations, and warns about mismatches.
+
+Then:
+
+```bash
+clawdbot gateway restart
+clawdbot status
+```
+
+## Common footguns (and how to avoid them)
+
+### Footgun: profile / state-dir mismatch
+
+If you ran the old gateway with a profile (or `CLAWDBOT_STATE_DIR`), and the new gateway uses a different one, you’ll see symptoms like:
+
+- config changes not taking effect
+- channels missing / logged out
+- empty session history
+
+Fix: run the gateway/service using the **same** profile/state dir you migrated, then rerun:
+
+```bash
+clawdbot doctor
+```
+
+### Footgun: copying only `clawdbot.json`
+
+`clawdbot.json` is not enough. Many providers store state under:
+
+- `$CLAWDBOT_STATE_DIR/credentials/`
+- `$CLAWDBOT_STATE_DIR/agents/<agentId>/...`
+
+Always migrate the entire `$CLAWDBOT_STATE_DIR` folder.
+
+### Footgun: permissions / ownership
+
+If you copied as root or changed users, the gateway may fail to read credentials/sessions.
+
+Fix: ensure the state dir + workspace are owned by the user running the gateway.
+
+### Footgun: migrating between remote/local modes
+
+- If your UI (WebUI/TUI) points at a **remote** gateway, the remote host owns the session store + workspace.
+- Migrating your laptop won’t move the remote gateway’s state.
+
+If you’re in remote mode, migrate the **gateway host**.
+
+### Footgun: secrets in backups
+
+`$CLAWDBOT_STATE_DIR` contains secrets (API keys, OAuth tokens, WhatsApp creds). Treat backups like production secrets:
+
+- store encrypted
+- avoid sharing over insecure channels
+- rotate keys if you suspect exposure
+
+## Verification checklist
+
+On the new machine, confirm:
+
+- `clawdbot status` shows the gateway running
+- Your channels are still connected (e.g. WhatsApp doesn’t require re-pair)
+- The dashboard opens and shows existing sessions
+- Your workspace files (memory, configs) are present
