How to Migrate from Notion Without Losing Your Data — A Complete Step-by-Step Guide
"I Want to Leave Notion But I'm Scared to Lose Everything"
Years of journals, KPI databases, expense logs, reading notes, project boards. It feels like moving would mean losing it all.
It won't. And the migration is simpler than you think — because most of your Notion data doesn't need to move at all.
Step 0: Classify What You're Actually Moving
Split your Notion data into three categories:
| Category | Examples | Migration Approach |
|---|---|---|
| Archive | Old journals, past projects | Leave in Notion as-is (free tier is fine) |
| Documents | Specs, notes, reference | Keep in Notion or move to Obsidian |
| Life log numbers | Weight, finances, skill hours | Move to Jibun Kaisha |
The key insight: most data stays in Notion. Converting Notion into an archive and switching only the active life-data recording is almost always the right call.
Step 1: Export Your Notion Data
How to Export
- Notion → Settings → Export all workspace content
- Format: Markdown & CSV
- Download and extract
Export Structure
workspace/
page-name.md
database-name/
database-name.csv
row-page.md
...
CSV files contain row data for each database. Markdown files contain page body text.
Step 2: Import Numeric Data into Jibun Kaisha
Here's how Notion databases map to Jibun Kaisha departments:
| Notion Database | Jibun Kaisha Department |
|---|---|
| Weight / sleep / exercise log | HR (Health) |
| Income / expense log | Finance |
| Freelance / side project tracker | Sales |
| Learning log / reading list | Product |
| SNS post planner | Marketing |
| Contracts / insurance notes | Legal |
CSV Import via Supabase (Beta)
You can import CSV directly through the Supabase dashboard:
- Supabase Dashboard → Table Editor
- Select target table (e.g.,
hr_records) - Import CSV → choose the exported file from Notion
- Confirm column mapping → run import
Common column mapping:
| Notion Column | Jibun Kaisha Column |
|---|---|
| Date | recorded_date |
| Value | value |
| Category | category |
| Note | note |
Step 3: Switch Your Daily Recording Habit
The most important migration step isn't moving old data — it's changing where you put new data today. Past data completeness matters less than a consistent new habit.
Recommended Transition Schedule
Week 1: Run both in parallel
- Enter new data in both Notion and Jibun Kaisha
- Get familiar with the dashboard layout
Weeks 2–3: Jibun Kaisha as primary
- Stop entering new data in Notion
- Flag anything missing and give feedback
Week 4+: Notion becomes archive only
- Reference old data in Notion as needed
- All new data lives in Jibun Kaisha
Step 4: Keep Notion as a Free Archive
Notion's free tier has limitations (1 guest, 5MB file uploads), but for personal archive access it's perfectly sufficient.
Old journals, project retrospectives, reading notes — leave them in Notion. They're still searchable. If you ever want to reference something from 2021, it's there.
You don't need to delete anything. Migration = "change where the new data goes." Not "move everything."
FAQ
Can I export AI University content to Notion?
No export needed — and no reason to. Jibun Kaisha's AI University covers 206+ providers with structured learning content that doesn't exist in Notion. It's net-new content, not a replacement for something you already have there.
What happens to my Notion subscription?
Jibun Kaisha is free ($0/month). Cancel Notion Plus ($10/month) and save $120/year. Keep the Notion free tier for archive access.
Does it work on mobile?
Yes. Jibun Kaisha is a PWA — add it to your iOS or Android home screen directly from the browser. No App Store installation needed.
What about data backup?
Supabase's PostgreSQL has automated backups. You can also manually export any table as CSV from the Supabase Dashboard. Your data is not locked in — PostgreSQL is an open format you can export at any time.
Summary: A Good Migration Isn't a Complete Migration
The goal isn't to move every byte of Notion data. It's to stop paying $10–18/month for a tool that wasn't designed for personal life management.
Change today: Start logging new life data in Jibun Kaisha
Leave in Notion: Historical archive, documents (free tier is fine)
Stop: Adding new life-log entries to Notion
That's it. Yesterday comparisons, 6-department dashboard, AI analysis — they're all there waiting.
