#### Step 2.3: Configuration Validation
```cmd
# Test Apache configuration
C:\xampp\apache\bin\httpd.exe -t
```
**Expected Result**: `Syntax OK`

### Phase 3: Service Restart and Testing (45 minutes)
```
Start Time: T+75
Duration: 45 minutes
```

#### Step 3.1: Service Management
- [ ] Stop Apache service gracefully
- [ ] Wait 30 seconds for complete shutdown
- [ ] Start Apache service
- [ ] Verify service is running without errors
- [ ] Check Apache error logs for any issues

#### Step 3.2: Basic Functionality Testing
- [ ] Test HTTP access (should redirect to HTTPS)
- [ ] Test HTTPS access with SSL certificate
- [ ] Verify certificate chain is complete
- [ ] Test website functionality over HTTPS
- [ ] Check browser security indicators

### Phase 4: Comprehensive Testing (30 minutes)
```
Start Time: T+120
Duration: 30 minutes
```

#### Step 4.1: SSL Certificate Verification
- [ ] Browser certificate validation
- [ ] SSL Labs test (if internet accessible)
- [ ] Certificate expiration date verification
- [ ] Mixed content checking

#### Step 4.2: Performance and Security Testing
- [ ] Page load time comparison
- [ ] Security headers verification
- [ ] HSTS functionality test
- [ ] Cross-browser compatibility check

## 4. Post-Deployment Tasks

### 4.1 Monitoring Setup
- [ ] Configure SSL certificate expiration monitoring
- [ ] Set up log monitoring for SSL errors
- [ ] Update monitoring dashboards
- [ ] Schedule regular SSL health checks

### 4.2 Documentation Update
- [ ] Update system documentation
- [ ] Record SSL certificate details and expiration
- [ ] Update network diagrams
- [ ] Create maintenance schedules

### 4.3 Communication
- [ ] Send deployment success notification
- [ ] Update status pages
- [ ] Notify stakeholders of completion
- [ ] Schedule post-deployment review

# ROLLBACK PLAN

## 1. Rollback Triggers

### 1.1 Critical Issues Requiring Immediate Rollback
- SSL certificate validation failures
- Website completely inaccessible via HTTPS
- Apache service failing to start
- Significant performance degradation (>50% slower)
- Critical functionality broken

### 1.2 Non-Critical Issues (Monitor and Fix)
- Minor SSL warnings in some browsers
- Non-critical mixed content warnings
- Minor performance impact (<20% slower)
- Cosmetic SSL indicator issues

## 2. Rollback Decision Matrix

| Issue Severity | Impact Level | Action Required | Time Frame |
