During migration to Lightning Knowledge, how can you ensure attachments are migrated with articles?

• A. Use the files-related list on each article to add files
• B. Post the files to the chatter feed on each article
• C. Upload the files like documents, then relate them to the migrated articles
• D. Use the Lightning Knowledge Migration Tool and choose "include files"

Answer: (A)

Attachments in Lightning Knowledge are managed as Files (ContentDocument) and are linked to articles through the Files related list. To guarantee they migrate with the articles, add the files to the Files related list on each article. This creates a direct, preserved link between the article and its attachments, so when the article moves to the Lightning Knowledge environment the associated files come along with it. Other approaches, like posting files to Chatter, uploading as Documents, or relying on a migration tool’s general option, don’t reliably preserve the exact article-file relationships. The Files related list explicitly establishes and preserves that relationship for the migration.
