Upgrade Technical Value Proposition
Reduce Support Costs
Policy-Based Management
– Pro-active, flexible administration
– Configuration Servers
Data Collection
– Used beyond performance monitoring/tuning; e.g. workload profiling, capacity planning
Plan Guides and validation
– Predictable query behavior
Important Trends Affecting SQL Server 2008 Usage
Consolidation
– Greater opportunities with tools like Resource Governor and Extended Key Management
– Providing flexible security in shared instances and shared servers
Virtualization
– Leverages Windows Server 2008 feature
– Easier to support since technologies are from single vendor
– Not just about dev/test and training
Data in the Cloud
– SQL Server Data Services
SQL Server 2008 Feature Pack

SQL Server Migration Assistant
• How to make an application originally written to run on Oracle, Access or Sybase to run on Microsoft SQL Server?
• Main challenge – different SQL dialects implemented by DBMS vendors
SSMA for Oracle
• Automates migration of Oracle databases to Microsoft SQL Server
→ Typically 80-90% of PL/SQL code gets converted immediately to Transact-SQL
→ Supports Oracle 8i, 9i,10g,11g
→ Target DB could be SQL Server 2005 or SQL Server 2008
→ Includes:• Migration Analyzer• Schema and Data Migrator • Migration Tester

Solution Architecture
Database Migration with SSMA
• Help migrate 2 clustered 32-bit SQL 2000 to clustered 64-bit SQL 2005 on new hardware with 26 user databases.
• Identify all code dependencies in over 58000 code files in over 20 applications.
• Identify all native SQL objects where deprecated terms and syntax occur, and provide code changes both as concepts and actual recoding.
• Develop and implement a test plan.
• SQL Profiler
• SQL Upgrade Advisor
• SQLCMD
• Quest Discovery Wizard for SQL Server
– Password Vulnerability Tool
• Red Gate SQL Compare
• Red Gate Data Compare
• SQL DB Search
• TextPad / regex
• Visual SourceSafe
• RML Utilities for SQL Server (Replay for Integration Testing)
– ReadTrace
– OStress
• Discover all SQL servers with dependencies
• Identify each application and their Database dependencies
• Trace activity of production workflows for as long as time and storage permit.
• Trace activity of all tests
• Use Upgrade Advisor to report on compatibility findings – must use both the servers and the trace files as inputs.
• The report generated identifies those constructs that were exercised only!
• Find keywords
– In the Server Objects
– In the Code
New keywords may need to be delimited (Bracketed) if used as object names depending on context.
– Develop “Code Chunks”
• Search for each of the deprecated terms / syntax in the source code and create a report for each item or class of item.
• Use regex to help limit false positives
– E.G Outer Join Syntax *= or =* versus /*=a note*/
• Map chunks to App owners
• Use a tool that can decrypt all “encrypted” SQL Objects if source is not available / legacy apps
• Trust the manufacturer of applications claiming SQL 2008 compliance, but test anyway…
• Create Unit tests of SQL Code when possible to make sure at least one case of new syntax works.
• Compare baseline performance to post conversion to watch for issues known in 2008.
