# Notion Migration Deep Dive ## Overview Comprehensive migration patterns for moving data to, from, and between Notion workspaces. This covers rate-limited bulk import from CSV/JSON with property mapping, full database export with pagination and block content extraction, cross-database sync with duplicate detection, data transformation patterns for Confluence and Google Docs content, and post-migration validation with integrity checks. All patterns respect Notion's 3 requests/second rate limit. ## Prerequisites - `@notionhq/client` v2+ installed (`npm install @notionhq/client`) - Python alternative: `notion-client` (`pip install notion-client`) - `p-queue` for rate-limited concurrency (`npm install p-queue`) - Source data access (CSV files, Confluence API, Google Docs API, etc.) - Target Notion database(s) created with matching property schema ## Instructions ### Step 1: Import CSV/JSON into Notion Database Map source data fields to Notion property types, create pages with rate limiting: ```typescript import { Client } from '@notionhq/client'; import { readFileSync } from 'fs'; import { parse } from 'csv-parse/sync'; import PQueue from 'p-queue'; const notion = new Client({ auth: process.env.NOTION_TOKEN! }); // Rate-limited queue: 3 requests/second (Notion's documented limit) const queue = new PQueue({ concurrency: 3, interval: 1000, intervalCap: 3 }); interface SourceRecord { name: string; status: string; priority: string; dueDate: string; tags: string;...
