Scenario 17: Migrate HarnessTap state to a new machine

Frequency: Rare · Status: Shipped (manual workflow — see Scenario 28 for one-command migration)

← Back to scenarios index

Use this when moving setups across laptops or onto a dev box. For a single archive that includes harness preferences and config, prefer Scenario 28.

Manual workflow with current commands:

# On the old machine
mkdir -p ./bundles
for p in $(harnesstap plugin list --format json | jq -r '.[].name'); do
  harnesstap migrate export "./bundles/$p" --plugin "$p" --embed-plugins
done

# Copy ./bundles/ to the new machine, then:
harnesstap init
for d in ./bundles/*/; do
  harnesstap migrate import "$d"
done
harnesstap harness set --main claude-code --aliases cursor,codex   # restore selection

--embed-plugins is recommended for portability so the new machine does not need to re-fetch marketplace plugin trees. This workflow does not currently carry over harness preferences or ~/.harnesstap/config.json; copy those by hand or use Scenario 28.
