When migrate beats update | plan / dry-run | JSON review | Gateway checks
v2026.4.26 hardens the operator story for bringing outside truth into OpenClaw: the openclaw migrate path adds plannable, dry-runnable, JSON-friendly diffs and bundled flows to import prompts, MCP endpoints, and skills that lived in Claude Code or Claude Desktop, with guardrails for credentials. Rental Macs also surface OPENCLAW_PLUGIN_DIR edge cases: read-only image layers, split roots, and cold-registry drift that look like “random install failures” until you align writable dependency trees with the v2026.4.25 registry guidance. This field guide targets teams doing machine moves, org merges, or first-class imports—not a routine patch day. It pairs a decision table (update alone vs migrate), an eight-step runbook, four copy-pasteable acceptance sentences, a VNC-focused verification grid for things SSH cannot finish, and cross-links to the official Docker article, launchd automation, and the ten-fix troubleshooting index so you know which doc owns which class of break.
The fastest way to bloat a ticket is to run migrate because the version number ticked, or to run openclaw update alone when the authoritative tree is split across two laptops and a shared bucket. Update keeps a single, healthy lineage current. Migrate is for structural movement: new host, new canonical state dir, or bulk merges from another toolchain. The six bullets below are common misfires; compare to the 3.x era migration article when you need historical contrast—4.26 leans on machine-readable plans instead of a five-line checklist alone.
Patch day, same node: openclaw update + openclaw doctor first; do not re-run migrate “just in case.”
New node: migrate plan/dry-run so relative paths, ports, and ~/.openclaw aliases are normalized before the Gateway starts on the wrong port map.
Claude workspace is the source of truth for prompts: use the 4.26 import merge, not a manual copy that leaves two divergent canons.
Plugin installs fail with EROFS-style errors: fix writable roots and OPENCLAW_PLUGIN_DIR before re-running openclaw update on a half-written tree.
Compose and bare metal both exist: re-read the Docker guide to avoid two Gateways fighting the same 18789 path.
launchd wraps your daemon: after a migrate, re-check the plist EnvironmentVariables with the launchd article so the interactive user and the daemon user stay coherent.
| What you see | Default move | Next hop | Avoid |
|---|---|---|---|
| Package out of date only | update + doctor | cache/permissions | full migrate |
| Fresh host, all paths new | migrate plan + JSON | diff secrets | Hand-copy JSON as root |
| MCP/Skill list lives in Claude | 4.26 merge import + dry-run | redact secrets in tickets | Double bookkeeping forever |
| Install fails read-only | writable dep root + repair | reopen Gateway | global chmod 777 |
| “Mixed” Gateway after upgrade | align binary + registry | 4.25 repair flow | Restart-only theatre |
Treat the steps as titles for your change request; on a rented Mac keep a VNC path open so the same interactive user that owns Gateway can also finish browser and macOS consent work.
Fingerprint: capture openclaw --version and a full openclaw doctor plus release channel (stable/beta) and whether you are inside a container.
Back up: claw backup or the snapshot flow your release notes mandate; for cloud hosts, snapshot the data volume too so rollback is one ticket, not archaeology.
Plan: run the migrate plan subcommand to list touched paths, providers, plugins, and the secrets plane.
Dry-run JSON: classify diffs: additive keys, canonical renames, and anything needing human pick-one resolution.
Claude merge review: compare instruction files, MCP cards, and skill archives after redaction; if two sources disagree, state which side wins in your internal wiki, not in Slack alone.
Writable root + OPENCLAW_PLUGIN_DIR: point dependency installs at a real writable location, then openclaw plugins repair and plugins doctor to align the cold registry story from 4.25.
Gateway: use local loopback or your reverse proxy to 18789; verify health, websockets, and the error triage in the ten-class guide before you declare success.
Freeze the CR: include dry-run versus apply diffs, rollback path, and explicit touch points with Docker or launchd owners.
openclaw --version && openclaw doctor claw backup openclaw migrate <plan|dry-run per your release notes> # review JSON, then apply openclaw plugins repair openclaw status
OPENCLAW_PLUGIN_DIR failures classify as writability and root design, not “transient network.”| Item | In VNC | Pass |
|---|---|---|
| Loopback / reverse proxy | Open the control UI with devtools | Stable WS, no 401 storm |
| System/browser consent | Finish prompts in the same user that owns the Gateway process | Prompts not deferred to “someone on VPN” |
| Sleep / power | Align with launchd expectations | No mid-demo nap on shared hosts |
| Plugin UI | Compare GUI list to CLI plugins list | Names/versions line up |
Volumes, loopback, container verification.

Point dependencies at a writable root, plugins repair, re-open Gateway.
Migrate is how you prove a config merge, not just hope a tarball landed intact. The hidden cost of skipping that proof is a split-brain where Gateway, launchd, and your Docker host disagree on ports and paths—tickets then oscillate between “it worked on my machine” and “it worked in SSH but not the UI,” which is expensive in calendar time and trust.
Self-hosting metal trades subscription dollars for capital, power contracts, and on-call for OS updates, while undersized laptops choke right when you parallelize imports, model pulls, and UI automation. A dedicated rentable Mac with both SSH and a reviewable GUI session keeps the boring uptime problems with the provider while you focus on the merge and security boundaries.
To stand up a node that can execute this article’s same-user VNC checks alongside CLI migrate flows, use VNCMac: the primary action below is the purchase page; for plans and public specs start from the home page and keep the Docker and launchd guides in the same run folder as this checklist.
