+
+# Schema importieren
+psql -h 192.168.45.3 -U customer -d customer -f sql/botkonzept_schema.sql

+# - BotKonzept-Customer-Registration-Workflow.json
+# - BotKonzept-Trial-Management-Workflow.json
+
+# 3. Credentials konfigurieren
+# SSH (PVE20): /root/.ssh/id_rsa
+# PostgreSQL: 192.168.45.3:5432/customer

+- Test: `curl -X POST https://n8n.userman.de/webhook/botkonzept-registration -H "Content-Type: application/json" -d '{"test":true}'`
+
+### 3. Website Deployment
+
+```bash
+# Setup-Script ausführen
+chmod +x setup_botkonzept.sh
+./setup_botkonzept.sh
+
+# Oder manuell:
+sudo mkdir -p /var/www/botkonzept
+sudo cp -r botkonzept-website/* /var/www/botkonzept/
+sudo chown -R www-data:www-data /var/www/botkonzept
+```
+
+**NGINX-Konfiguration:**
+
+```nginx
+server {
+    listen 80;
+    server_name botkonzept.de www.botkonzept.de;
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name botkonzept.de www.botkonzept.de;
+    
+    ssl_certificate /etc/letsencrypt/live/botkonzept.de/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/botkonzept.de/privkey.pem;
+    
+    root /var/www/botkonzept;
+    index index.html;
+    
+    location / {
+        try_files $uri $uri/ =404;
+    }
+    
+    # Security headers
+    add_header X-Frame-Options "SAMEORIGIN" always;
+    add_header X-Content-Type-Options "nosniff" always;
+    add_header X-XSS-Protection "1; mode=block" always;
+}
+```
+
+### 4. SSL-Zertifikat
+
+```bash
+# Let's Encrypt installieren
+sudo apt-get install certbot python3-certbot-nginx
+
+# Zertifikat erstellen
+sudo certbot --nginx -d botkonzept.de -d www.botkonzept.de
+
+# Auto-Renewal testen
+sudo certbot renew --dry-run
+```
+
+## ✅ Post-Deployment Tests
+
+### 1. Datenbank-Tests
+
+```sql
+-- Kunden-Tabelle testen
+INSERT INTO customers (email, first_name, last_name, status)
+VALUES ('test@example.com', 'Test', 'User', 'trial')
+RETURNING *;
+
+-- View testen
+SELECT * FROM customer_overview;
+
+-- Cleanup
+DELETE FROM customers WHERE email = 'test@example.com';
+```
+
+### 2. Workflow-Tests
+
+```bash
+# Registration Webhook testen
+curl -X POST https://n8n.userman.de/webhook/botkonzept-registration \
+  -H "Content-Type: application/json" \
+  -d '{
+    "firstName": "Max",
+    "lastName": "Mustermann",
+    "email": "test@example.com",
+    "company": "Test GmbH",
+    "terms": true

+-- Trials die heute ablaufen
+SELECT * FROM trials_expiring_soon WHERE days_remaining < 1;
+
+-- E-Mails der letzten 24h
+SELECT email_type, COUNT(*) 
+FROM emails_sent 
+WHERE sent_at >= NOW() - INTERVAL '24 hours'

+# Memory-Usage
+free -h
+
+# Load Average
+uptime
+```

+
+## 📝 Backup-Strategie
+
+### Datenbank-Backup
+
+```bash
+# Tägliches Backup
+0 2 * * * pg_dump -h 192.168.45.3 -U customer customer > /backup/botkonzept_$(date +\%Y\%m\%d).sql
+
+# Backup-Retention (30 Tage)
+find /backup -name "botkonzept_*.sql" -mtime +30 -delete
+```
+
+### LXC-Backup
+
+```bash
+# Proxmox Backup
+vzdump --mode snapshot --compress gzip --storage backup-storage
+```
+
+### Website-Backup
+
+```bash
+# Git-Repository
+cd /var/www/botkonzept
+git init
+git add .
+git commit -m "Website backup $(date)"
+git push origin main
+```
+
+## 🚨 Rollback-Plan
+
+### Bei Problemen mit Workflows
+
+1. Workflows deaktivieren
+2. Alte Version wiederherstellen
+3. Credentials prüfen
+4. Neu aktivieren
+
+### Bei Datenbank-Problemen
+
+```bash
+# Backup wiederherstellen
+psql -h 192.168.45.3 -U customer customer < /backup/botkonzept_YYYYMMDD.sql
+```
+
+### Bei Website-Problemen
+
+```bash
+# Alte Version wiederherstellen
+git checkout HEAD~1
+sudo cp -r botkonzept-website/* /var/www/botkonzept/
+```
