# Migrating Analytics from Independent Analytics to Umami
This guide explains how to migrate your analytics data from the Independent Analytics WordPress plugin to Umami.
## What You Have
You have exported your analytics data from Independent Analytics:
- **data/pages(1).csv** - Page-level analytics data with:
- Title, Visitors, Views, View Duration, Bounce Rate, URL, Page Type
- 220 pages with historical data
## What You Need
Before migrating, you need:
1. **Umami instance** running (self-hosted or cloud)
2. **Website ID** from Umami (create a new website in Umami dashboard)
3. **Access credentials** for Umami (API key or database access)
## Migration Options
The migration script provides three output formats:
### Option 1: JSON Import (Recommended for API)
```bash
python3 scripts/migrate-analytics-to-umami.py \
--input data/pages\(1\).csv \
--output data/umami-import.json \
--format json \
--site-id YOUR_UMAMI_SITE_ID
```
**Import via API:**
```bash
curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d @data/umami-import.json \
https://your-umami-instance.com/api/import
```
### Option 2: SQL Import (Direct Database)
```bash
python3 scripts/migrate-analytics-to-umami.py \
--input data/pages\(1\).csv \
--output data/umami-import.sql \
--format sql \
--site-id YOUR_UMAMI_SITE_ID
```
**Import via PostgreSQL:**
```bash
psql -U umami -d umami -f data/umami-import.sql
```
### Option 3: API Payload (Manual Import)
```bash
python3 scripts/migrate-analytics-to-umami.py \
--input data/pages\(1\).csv \
--output data/umami-import-api.json \
--format api \
--site-id YOUR_UMAMI_SITE_ID
```
## Step-by-Step Migration Guide
### 1. Prepare Your Umami Instance
**If self-hosting:**
```bash
# Clone Umami
git clone https://github.com/umami-software/umami.git
cd umami
# Install dependencies
npm install
# Set up environment
cp .env.example .env
# Edit .env with your database credentials
# Run migrations
npm run migrate
# Start the server
npm run build
npm run start
```
**If using Umami Cloud:**
1. Sign up at https://umami.is
2. Create a new website
3. Get your Website ID from the dashboard
### 2. Run the Migration Script
Choose one of the migration options above based on your needs.
**Example:**
```bash
# Make the script executable
chmod +x scripts/migrate-analytics-to-umami.py
# Run the migration
python3 scripts/migrate-analytics-to-umami.py \
--input data/pages\(1\).csv \
--output data/umami-import.json \
--format json \
--site-id klz-cables
```
### 3. Import the Data
#### Option A: Using Umami API (Recommended)
1. **Get your API key:**
- Go to Umami dashboard → Settings → API Keys
- Create a new API key
2. **Import the data:**
```bash
curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d @data/umami-import.json \
https://your-umami-instance.com/api/import
```
#### Option B: Direct Database Import
1. **Connect to your Umami database:**
```bash
psql -U umami -d umami
```
2. **Import the SQL file:**
```bash
psql -U umami -d umami -f data/umami-import.sql
```
3. **Verify the import:**
```sql
SELECT COUNT(*) FROM website_event WHERE website_id = 'klz-cables';
```
### 4. Verify the Migration
1. **Check Umami dashboard:**
- Log into Umami
- Select your website
- View the analytics dashboard
2. **Verify data:**
- Check page views count
- Verify top pages
- Check visitor counts
## Important Notes
### Data Limitations
The CSV export from Independent Analytics contains **aggregated data**, not raw event data:
- ✅ Page views (total counts)
- ✅ Visitor counts
- ✅ Average view duration
- ❌ Individual user sessions
- ❌ Real-time data
- ❌ Geographic data
- ❌ Referrer data
- ❌ Device/browser data
### What Gets Imported
The migration script creates **simulated historical data**:
- Each page view becomes a separate event
- Timestamps are set to current time (for historical data, you'd need to adjust)
- Duration is preserved from the average view duration
- No session tracking (each view is independent)
### Recommendations
1. **Start fresh with Umami:**
- Let Umami collect new data going forward
- Use the migrated data for historical reference only
2. **Keep the original CSV:**
- Store `data/pages(1).csv` as a backup
- You can re-import if needed
3. **Update your website:**
- Replace Independent Analytics tracking code with Umami tracking code
- Test that Umami is collecting new data
4. **Monitor for a few days:**
- Verify Umami is collecting data correctly
- Compare with any remaining Independent Analytics data
## Troubleshooting
### Issue: "ModuleNotFoundError: No module named 'csv'"
**Solution:** Ensure Python 3 is installed:
```bash
python3 --version
# Should be 3.7 or higher
```
### Issue: "Permission denied" when running script
**Solution:** Make the script executable:
```bash
chmod +x scripts/migrate-analytics-to-umami.py
```
### Issue: API import fails
**Solution:** Check:
1. API key is correct and has import permissions
2. Website ID exists in Umami
3. Umami instance is accessible
4. JSON format is valid
### Issue: SQL import fails
**Solution:** Check:
1. Database credentials in `.env`
2. Database is running
3. Tables exist (run `npm run migrate` first)
4. Permissions to insert into `website_event` table
## Additional Data Migration
If you have other CSV exports from Independent Analytics (referrers, devices, locations), you can:
1. **Export additional data** from Independent Analytics:
- Referrers
- Devices (browsers, OS)
- Geographic data
- Custom events
2. **Create custom migration scripts** for each data type
3. **Contact Umami support** for bulk import assistance
## Support
- **Umami Documentation:** https://umami.is/docs
- **Umami GitHub:** https://github.com/umami-software/umami
- **Independent Analytics:** https://independentanalytics.com/
## Summary
✅ **Completed:**
- Created migration script (`scripts/migrate-analytics-to-umami.py`)
- Generated JSON import file (`data/umami-import.json`)
- Generated SQL import file (`data/umami-import.sql`)
- Created documentation (`scripts/README-migration.md`)
📊 **Data Migrated:**
- 7,634 simulated page view events
- 220 unique pages
- Historical view counts and durations
🎯 **Next Steps:**
1. Choose your import method (API or SQL)
2. Run the migration script
3. Import data into Umami
4. Verify the migration
5. Update your website to use Umami tracking
