# Evernote Migration Deep Dive ## Current State !`npm list 2>/dev/null | head -5` ## Overview Comprehensive guide for migrating data to and from Evernote, including ENEX export/import, bulk API operations, format conversions (ENML to Markdown, HTML to ENML), and data integrity verification. ## Prerequisites - Understanding of Evernote data model (Notes, Notebooks, Tags, Resources) - Source/target system access credentials - Sufficient API quota for migration volume - Backup strategy in place before starting ## Instructions ### Step 1: Migration Planning Assess the migration scope: count notes, notebooks, tags, and total resource size. Estimate API call count and quota consumption. Plan for rate limits (add delays between operations). ```javascript async function assessMigration(noteStore) { const notebooks = await noteStore.listNotebooks(); const tags = await noteStore.listTags(); let totalNotes = 0; for (const nb of notebooks) { const filter = new Evernote.NoteStore.NoteFilter({ notebookGuid: nb.guid }); const spec = new Evernote.NoteStore.NotesMetadataResultSpec({}); const result = await noteStore.findNotesMetadata(filter, 0, 1, spec); totalNotes += result.totalNotes; } return { notebooks: notebooks.length, tags: tags.length, totalNotes, estimatedApiCalls: totalNotes * 2 + notebooks.length + tags.length, estimatedTimeMinutes: Math.ceil((totalNotes * 2 * 200) / 60000) // 200ms per call }; } ``` ### Step 2: Export fr...
