## Configuration Changes Summary
### Removed (11 deprecated options)
- `log-destination`
- `fast-sync-min-peers` (incompatible with FULL sync)
- `database-path`
- `trie-logs-enabled`
- `accounts-enabled`
- `max-remote-initiated-connections`

---
## Next Steps for Deployment
### Step 1: Pre-Deployment Verification
```bash
# Validate all configs
./scripts/validate-besu-config.sh
# Verify no deprecated options
./scripts/cleanup-besu-deprecated-options.sh --dry-run
# Audit configs against templates
./scripts/audit-besu-configs.sh
```
**Expected**: All validations pass ✅
---
### Step 2: Deploy Configurations
```bash
# Dry-run first (recommended)
./scripts/deploy-besu-configs.sh --dry-run
# Deploy to all nodes (when ready)
./scripts/deploy-besu-configs.sh
```
**Deployment Order**:
1. **Validators** (1000-1004) - First
2. **Sentries** (1500-1503) - Second
3. **RPC Nodes** (2500+) - Last
**Process**:
- Backs up existing configs
- Copies cleaned configs to nodes
- Validates configs before deployment
- Restarts services gracefully
- Verifies services start successfully
---
### Step 3: Monitor Deployment
Follow `docs/04-configuration/BESU_DEPLOYMENT_MONITORING.md`:
**Immediate (0-1 hour)**:
- ✅ Verify all services started
- ✅ Check for configuration errors
- ✅ Verify no restart loops
- ✅ Check logging levels
**Short-term (1-6 hours)**:
- ✅ Monitor service status
- ✅ Verify network connectivity
- ✅ Test consensus (validators)
- ✅ Test archive queries (sentries)
**Medium-term (6-48 hours)**:
- ✅ Monitor resource usage
- ✅ Check peer connections
- ✅ Verify sync status
- ✅ Monitor performance
---
### Step 4: Verify Configuration
```bash
# Verify logging levels on each node type
# Validators should show WARN logs
pct exec 1000 -- journalctl -u besu-validator.service -n 20
# Sentries should show INFO logs
pct exec 1500 -- journalctl -u besu-sentry.service -n 20
# RPC nodes should show WARN logs
pct exec 2500 -- journalctl -u besu-rpc.service -n 20
# Check for configuration errors
pct exec 1000 -- journalctl -u besu-validator.service | grep -i "error\|unknown option"
```
**Expected**: No configuration errors ✅
