Migrate a whole ArcGIS Hub site into a PortalJS Arc portal end-to-end. Harvests the Hub /data.json (DCAT-US) inventory, exports every FeatureService layer through the ArcGIS REST query API with resultOffset paging, converts each to the serverless dual tier (PMTiles render + GeoParquet query) with tabular items to Parquet, pushes everything to Cloudflare R2 via Git LFS, appends dual-tier datasets.json entries, and writes a source-vs-derived parity report. Use to move a City or sector ArcGIS Hub open-data portal onto PortalJS with no server-side compute.

1# ArcGIS Hub → PortalJS23## Overview45Migrate an entire **ArcGIS Hub** open-data site into a **PortalJS Arc** portal in one pass.6Every Hub site is machine-readable — a DCAT-US catalog at `/data.json`, with every dataset7backed by an ArcGIS REST FeatureService — so migration is a **harvest → export → convert →8publish → verify** pipeline that runs almost fully automated on the operator's machine, no9server-side compute. The tooling is the reusable `arcgis-to-portaljs` migrator: input is one10Hub URL, output is a ready-to-deploy PortalJS catalog plus a parity report.1112The skill is an orchestrator: it reuses the DCAT-US harvest from `portaljs-migrate`, the13`ogr2ogr`/`tippecanoe`/`duckdb` dual-tier conversion from `portaljs-add-geo`, and the bulk14Git-LFS → R2 push from `portaljs-migrate`. Its novel parts are the FeatureService REST export15loop (paged features, not just a link) and the source-vs-derived parity report.1617## Prerequisites1819- A scaffolded PortalJS portal whose template ships `components/MapPreview.tsx` and20 `components/GeoQuery.tsx` (PR #1647 or later). Run `portaljs-new-portal` first if none.21- Native CLIs: **GDAL** (`ogr2ogr`, `ogrinfo`), **tippecanoe**, **duckdb** (with `spatial`),22 and **jq**. macOS: `brew install gdal tippecanoe duckdb jq`; Debian/Ubuntu:23 `apt-get install gdal-bin duckdb jq` plus tippecanoe (apt or build from source); Windows via24 WSL. The skill hard-stops with the install hint if any is missing.25…
