## 🎯 **VERSION UPDATE STRATEGY**

### **✅ RECOMMENDED: Update to Latest Stable Versions**

**Rationale:**
- ✅ **Security patches** - Latest versions include security updates
- ✅ **Performance improvements** - Newer versions are often faster
- ✅ **Feature enhancements** - Access to latest features
- ✅ **Bug fixes** - Resolved known issues
- ✅ **Long-term support** - Better maintenance

### **⚠️ CONSIDERATIONS:**
- **Test thoroughly** before updating production
- **Backup before updates** - Always have rollback capability
- **Update one service at a time** - Minimize risk
- **Monitor after updates** - Ensure stability

## 🚨 **SERVICES TO UPDATE CAREFULLY**

### **⚠️ High-Risk Updates (Test Extensively):**
- [ ] **Nextcloud**: Major version updates can break apps
- [ ] **PostgreSQL**: Database schema changes possible
- [ ] **MariaDB**: Database schema changes possible
- [ ] **AppFlowy**: Complex application, test thoroughly

### **✅ Low-Risk Updates (Standard Process):**
- [ ] **Redis**: Usually safe to update
- [ ] **Mosquitto**: MQTT broker updates are typically safe
- [ ] **Jellyfin**: Media server updates are usually safe
- [ ] **AdGuard**: DNS filtering updates are typically safe
