SQL Server 2022 Upgrade Solution

Modular Architecture Presentation for DBAs

Slide 1: Title Slide

SQL Server 2022 Upgrade Solution Modular PowerShell Architecture using dbatools

Presented to: DBA Team Date: October 2025 Solution: Side-by-Side Instance Upgrade

Slide 2: Summary

Key Benefits

  • ✅ 100% dbatools - No T-SQL dependencies
  • ✅ Modular Design - 6 specialized modules like dbatools
  • ✅ Complete Database Migration - Entire databases as units
  • ✅ Production Ready - Comprehensive logging, error handling, WhatIf mode
  • ✅ Safe Operations - Never drops anything, idempotent design

Value

  • Reduces upgrade risk through proven dbatools methods
  • Accelerates migration timeline with automated processes
  • Ensures data integrity with complete database approach
  • Provides audit trail with comprehensive logging

Slide 3: Architecture Overview

Modular Design (6 Modules)

Start-SQLServerUpgrade.ps1 (Main Orchestrator)
├── SQLUpgrade.Logging.psm1      # Centralized logging
├── SQLUpgrade.Connection.psm1   # Connection management
├── SQLUpgrade.Database.psm1     # Database operations
├── SQLUpgrade.Encryption.psm1   # TDE & encryption support
├── SQLUpgrade.Migration.psm1    # Complete database migration
└── SQLUpgrade.PostUpgrade.psm1  # Maintenance tasks

Design Principles

  • Single Responsibility - Each module handles one functional area
  • Reusability - Modules can be used independently
  • Maintainability - Easy to update and extend
  • Testability - Individual modules can be unit tested

Slide 4: Core Functionality

Database Migration Approach

  • Complete Database Copy using Copy-DbaDatabase
  • Backup/Restore Method for data integrity
  • Preserves All Objects - tables, views, procedures, functions, triggers, users, roles
  • Maintains Dependencies - referential integrity preserved
  • Encryption Support - Handles TDE and encrypted objects

Safety Features

  • WhatIf Mode - Preview changes without execution
  • Idempotent Operations - Safe to run multiple times
  • Never Drops Objects - Only creates/adds
  • Robust Error Handling - Graceful failure recovery
  • Connection Management - Persistent, reliable connections

Slide 5: Logging & Monitoring

Comprehensive Logging

  • File-based Logging - Timestamped detailed logs
  • Windows Event Log - Integration for monitoring systems
  • Error Separation - Dedicated error log files
  • Multiple Log Levels - Information, Warning, Error

Monitoring Capabilities

  • Real-time Progress - Console output during execution
  • Audit Trail - Complete record of all operations
  • Error Tracking - Detailed error messages and stack traces
  • Performance Metrics - Timing and success/failure rates

Slide 6: Pre-Upgrade Validation

Automated Checks

  • Connectivity Testing - Validates connections to both instances
  • Collation Compatibility - Ensures source/target compatibility
  • Encryption Detection - Identifies TDE and encrypted objects
  • Database Enumeration - Filters user databases (excludes system DBs)

Prerequisites Validation

  • dbatools Module - Ensures required PowerShell module is available
  • Permissions Check - Validates sysadmin rights on both instances
  • Network Connectivity - Tests communication between instances
  • Disk Space - Verifies sufficient space for migration

Slide 7: Post-Upgrade Tasks

Automated Maintenance

  • Database Integrity - DBCC CHECKDB for corruption detection
  • Compatibility Level - Updates to SQL Server 2022 (160)
  • Statistics Update - Refreshes query optimization statistics
  • Index Maintenance - Rebuilds indexes for optimal performance

Quality Assurance

  • Verification Steps - Confirms successful migration
  • Performance Baseline - Establishes post-upgrade metrics
  • Error Reporting - Identifies any issues requiring attention
  • Documentation - Records all completed tasks

Slide 8: Usage Examples

Basic Upgrade Command

.\Start-SQLServerUpgrade.ps1 `
    -SourceInstance "SQL2019\PROD" `
    -TargetInstance "SQL2022\PROD" `
    -Databases "All" `
    -IncludeEncryption

WhatIf Preview Mode

.\Start-SQLServerUpgrade.ps1 `
    -SourceInstance "SQL2019\PROD" `
    -TargetInstance "SQL2022\PROD" `
    -Databases @("CustomerDB", "OrdersDB") `
    -WhatIf

Individual Module Usage

Import-Module .\Modules\SQLUpgrade.Connection.psm1
$connection = Test-InstanceConnectivity -Instance "SQL2019\PROD"

Slide 9: Security & Compliance

Security Features

  • No Credential Storage - Uses Windows Authentication
  • Encryption Support - Handles TDE databases and encrypted objects
  • Audit Logging - Windows Event Log integration
  • Safe Operations - Never drops or deletes data

Compliance Benefits

  • Change Tracking - Complete audit trail of all operations
  • Rollback Capability - Side-by-side approach allows easy rollback
  • Documentation - Automated logging for compliance reporting
  • Validation - Pre and post-upgrade verification steps

Slide 10: Implementation Timeline

Phase 1: Preparation (1-2 days)

  • Install dbatools on management server
  • Validate connectivity and permissions
  • Test WhatIf mode on development environment
  • Review and customize logging paths

Phase 2: Development/Test (3-5 days)

  • Execute upgrade on development instances
  • Validate functionality and performance
  • Test rollback procedures
  • Document any environment-specific configurations

Phase 3: Production (1 day)

  • Execute production upgrade during maintenance window
  • Monitor progress through logging
  • Validate post-upgrade tasks completion
  • Confirm application connectivity

Slide 11: Risk Mitigation

Low-Risk Approach

  • Side-by-Side Installation - Original instance remains untouched
  • dbatools Proven Methods - Industry-standard migration tools
  • Complete Testing - WhatIf mode for thorough validation
  • Comprehensive Logging - Full visibility into all operations

Rollback Strategy

  • Original Instance Preserved - Can switch back immediately
  • Application Connection Strings - Simple DNS/connection changes
  • Data Synchronization - Can sync changes if needed
  • Minimal Downtime - Quick cutover process

Slide 12: Success Metrics

Technical Metrics

  • Migration Success Rate - Percentage of databases successfully migrated
  • Data Integrity - Zero data loss or corruption
  • Performance Baseline - Post-upgrade performance meets or exceeds baseline
  • Error Rate - Minimal errors during migration process

Business Metrics

  • Downtime Duration - Actual vs. planned maintenance window
  • Application Availability - Time to restore full functionality
  • User Impact - Minimal disruption to end users
  • Cost Efficiency - Reduced manual effort through automation

Slide 13: Support & Maintenance
