+
+## 📋 MIGRATION STRATEGY & IMPLEMENTATION PLAN
+
+### Phase 1: Pre-Migration Assessment (1 day)
+```bash
+# Database compatibility verification
+1. Schema compatibility check
+2. Data integrity validation
+3. Performance baseline establishment
+4. Backup and rollback procedures
+5. Downtime window planning
+```
+
+### Phase 2: Migration Execution (2-4 hours)
+```sql
+-- Step 1: Full database backup
+mysqldump --single-transaction --routines --triggers desk_descomplicar_pt > backup_$(date +%Y%m%d_%H%M%S).sql
+
+-- Step 2: Install MariaDB 11.4 LTS
+-- (System-specific installation commands)
+
+-- Step 3: Import data to MariaDB
+mysql -u root -p desk_descomplicar_pt < backup_$(date +%Y%m%d_%H%M%S).sql
+
+-- Step 4: Verify data integrity
+SELECT COUNT(*) FROM tbldeskmoloni_mapping;
+SELECT COUNT(*) FROM tbldeskmoloni_sync_queue;
+SELECT COUNT(*) FROM tbldeskmoloni_sync_log;
+
+-- Step 5: Performance optimization for MariaDB
+OPTIMIZE TABLE tbldeskmoloni_mapping;
+OPTIMIZE TABLE tbldeskmoloni_sync_queue;
+OPTIMIZE TABLE tbldeskmoloni_sync_log;
+```
+
+### Phase 3: Performance Validation (1 day)
+```php
+// Performance testing suite
+class MariaDBMigrationValidator {
+    public function validatePerformance() {
+        $tests = [
+            'insert_performance' => $this->testInsertOperations(100),

+class DatabaseMigrationTestSuite {
+    
+    // Test 1: Data Integrity Verification
+    public function testDataIntegrity() {
+        return [
+            'mapping_records_count' => $this->validateMappingCount(),
+            'sync_log_integrity' => $this->validateSyncLogs(),

+            'memory_usage' => $this->monitorMemoryConsumption()
+        ];
+    }
+}
+```
+
+### Rollback Strategy (Safety First - Sacred Rule 5)
+```sql
+-- Emergency rollback procedure
+-- 1. Stop application services
+sudo systemctl stop apache2
+
+-- 2. Restore MySQL backup
+mysql -u root -p -e "DROP DATABASE desk_descomplicar_pt;"
+mysql -u root -p -e "CREATE DATABASE desk_descomplicar_pt;"
+mysql -u root -p desk_descomplicar_pt < backup_pre_migration.sql
+
+-- 3. Restart services
+sudo systemctl start apache2
+
+-- 4. Verify restoration
+SELECT COUNT(*) FROM tbldeskmoloni_mapping;
+```
+
+---
+
+## 📊 MONITORING & MAINTENANCE PLAN
+
+### Performance Monitoring Setup
+```bash
+# MariaDB performance monitoring script
+#!/bin/bash
+# Monitor key performance metrics for desk-moloni
+
+# Database performance metrics
+mysql -e "SHOW GLOBAL STATUS LIKE 'Queries'" >> /var/log/mariadb-performance.log
+mysql -e "SHOW GLOBAL STATUS LIKE 'Threads_connected'" >> /var/log/mariadb-performance.log
+mysql -e "SHOW GLOBAL STATUS LIKE 'Innodb_buffer_pool_read_requests'" >> /var/log/mariadb-performance.log
+
+# Desk-moloni specific metrics
+mysql -e "SELECT COUNT(*) as queue_pending FROM tbldeskmoloni_sync_queue WHERE status='pending'" >> /var/log/desk-moloni-metrics.log
+mysql -e "SELECT AVG(execution_time_ms) as avg_sync_time FROM tbldeskmoloni_sync_log WHERE created_at > NOW() - INTERVAL 1 HOUR" >> /var/log/desk-moloni-metrics.log
+```
+
+### Automated Health Checks
