3. Agenda
DACFx & Import / Export Service
SQL Server Data Tools
Other Migration Tools
Best Practices

5. Terminology
DAC – Data-tier Application
DACFx – DAC Framework
DACPAC –Schema only artifact
BACPAC – Deployment artifact containing schema and data

6. DAC Fx (DAC Framework)
DACFX client library installed automatically by SQL Server
No need for additional client libraries or MSIs
Wizards provided in SSMS to create and distribute DACPAC/BACPAC
Simplify packaging and deployment of databases

7. Import/Export Service
Import/Export between Windows Azure SQL Database and Blob Storage
Export and Import a logical backup file (BACPAC) containing schema definition and
data
Copy databases between SQL Database servers
Migrate from SQL Server on-premises to SQL Database

8. Architecture
Blob Storage
SQL Database Service Import / Export
SQL Database
DACFx Import/Export Service BACPAC

Upload/
Download
SQL Server 2005, 2008/R2, 2012
DACFx
Client-side Tools (SSMS and SSDT)
Client-side Import/Export

9. Service Benefits
Automated Service Endpoint
Integrated Portal Experience
Performance via data center side deployment
Connection Resiliency
Selective Export
Progressive Status Reporting

10. Requirements
SQL Server 2012 Storage Account
All necessary components are installed SQL Database Server
SQL Server* 2008 R2, 2008, 2005
Data-tier Application Framework
ScriptDOM
System CLR Types

11. Limitations
SQL Variant Data Type
No transactional consistency
Database must be SQL Database compatible
Secrets not migrated (passwords, encrypted procs, etc.)
No support for SQL Server 2000

14. SQL Server Data Tools
Declarative, model based database development
Integrated Tools
Application development integration
SQL Server and SQL Database Support
Connected and offline with local testing
Change Detection

15. SQL Server Data Tools
Connected Development
Project Based Development
Schema Deployment

18. Additional Tools
Generate Scripts Wizard
BCP
SSIS
SQL Database Migration Wizard
Migration Assistants

20. Migration considerations
Data Size
Data Types
Frequency
Transactional Consistency
Technology Proficiency

Checks
BCP No N/A Yes Good • Efficient transfer of data to existing table
SSMS Generate • Good for smaller databases
Yes Some Yes Poor • Has explicit option for SQL Database script generation
Scripts wizard
• Simple UI on top of SSIS; also available in SSMS
SQL Server Import &
No N/A Yes Good
Export Data
• Most flexibility
SSIS No N/A Yes Good
• Great capabilities; e.g. evaluate trace files
SQL Database
Yes Yes Yes Good • Open source on CodePlex;
Migration Wizard • Not supported by MSFT
• Entity containing all database objects including data
DAC (BACPAC) Yes Yes Yes Good • Full SQL Database support
DAC Database • Export/import of DAC plus data with DAC framework
Yes Yes Yes Good • Service for cloud-only support coming soon
Import/Export
• Create transactionally consistent copy of SQL Database
SQL Database Copy Yes N/A Yes Good instances
• Currently within the same data center
