20-Apr-2026 — Image Migration → Content Migration

GitHub #206 — commit 1529096

The admin migration tool now handles all external document types — PDFs, Word, Excel and other files — not just images. The admin menu and route are renamed from Image Migration to Content Migration, with the old URL redirecting automatically.

What's scanned

The scanner now picks up external URLs from:

• markdown links [text](https://ngx-ramblers.org.uk/url)
• HTML links <a href>
• image tags and markdown images
• href fields on content columns

Each result is tagged with a document type (image, pdf, spreadsheet, document, other) and rendered with an appropriate coloured badge and icon.

Scan Results

Scan Results for kentramblers.org.uk — 478 external items across 225 sources. Coloured badges distinguish PDFs from Word documents; Select All / Deselect All / Migrate N Selected Items live in the toolbar.

Activity

The Activity tab streams each step of a migration in real time. PDFs download to S3 as-is (no resizing); HTTP failures are surfaced inline but don't halt the batch.

Notes

• Non-image files are uploaded to S3 as-is. "Auto Resize Images" only applies to images.
• Link rewriting covers <img> / ![]() and <a href> / [text](https://ngx-ramblers.org.uk/url) patterns, plus column.href.
• The old admin/image-migration URL automatically redirects to admin/content-migration.
• A deployment migration (20260329000000) renames the admin menu item automatically.

Renames (for contributors)

Everything with "image" in its name has been broadened to "content":

• Components — ImageMigrationTab → ContentMigrationTab; ImageMigrationGroupComponent → ContentMigrationGroupComponent
• Types — ExternalImageReference → ExternalContentReference (adds documentType); new ContentMigrationDocumentType enum (IMAGE, PDF, SPREADSHEET, DOCUMENT, OTHER)
• Fields — images → items, totalImages → totalItems, processedImages → processedItems, currentImage → currentItem, migratedImages → migratedItems, failedImages → failedItems
• Helpers — extractImageUrlsFromMarkdown → extractExternalUrlsFromText (also matches links), extractImagesFromColumn → extractUrlsFromColumn (also scans href), scanForExternalImages → scanForExternalContent, downloadExternalImage → downloadExternalContent
• Websocket events — IMAGE_MIGRATION_* → CONTENT_MIGRATION_*
• New helpers — documentTypeFromUrl(), isExternalDocumentUrl()
