A. Prepare a single .csv file that can be used to migrate all articles types at once and include with a properties file in a .zip for import.

B. Verify that each article type has field level security on all fields set to read-only prior to import, in order to prevent any loss of data.

C. Ensure that each existing article type has a corresponding Salesforce Knowledge article type that matches its structure and content.

D. Convert any articles containing HTML into plain text before importing because HTML is NOT supported in any article field types.
