Components Database Engine Reporting Services Notification Services Analysis Services Data Transformation Services FullText Editions Workgroup Express Standard Developer Enterprise Platforms 32-bit 64-bit (IA64 and x64)

Updates an existing installation while preserving user data Instance name remains the same Automated process

Pros Easier & Automatic Generally fast overall No extra hardware Applications remain pointing to same server/database name Cons Less granular control Instance remains offline during part of upgrade Not best practice for all components Complex rollback strategy

Install new instance of SQL Server Database objects are copied between instances Can be same server (named instance) or different server Mostly Manual process

Pros More granular control over upgrade process Can be used to perform test migration Ability to run systems side- by-side for testing and verification Relatively straightforward rollback Strategy Can leverage failover/switchover to reduce downtime Cons Usually require additional hardware Server/database name changes Not practical for VLDB unless utilizing SAN

Analyzes Configuration and objects within installed components Trace files (captured using Profiler/SQL Trace) T-SQL scripts (any script file) Generates Detailed Issue Report: Before – potential showstoppers, must resolve before upgrading After – should be resolved after completing upgrade Anytime Advisory – notices and/or warnings

Analyzes SQL Server 2000/2005 database, trace files and script files Read-only operation, can be CPU intensive Supports remote execution Supports default and named instance Requires.NET framework 2.0 sp1 or later Download latest version from web!

UA does not detect everything: Dynamic SQL Meta-data driven applications (both during application setup and regular use) Changes in system objects (stored procedures, functions, tables, etc…) but uses the same name UA does not have rules for all known issues or any “yet to be known” issues

Developed in conjunction with Scalability Experts Available for upgrades to SQL Server2005 and SQL Server 2008

Capture realistic workload from test/production Establish a baseline in ACT environment: Restore SQL Server 2000/2005 database environment Replay captured trace and record baseline data Determine functional and performance measures of same application on SQL Server bit Upgrade database to SQL Server 2008 Replay captured trace and record functional and performance data Repeat for x64 if required or just test against x64

Support for SQL 2000 Set by default after upgrade Trace flags for deprecated events

Test with Compatibility Level 10 Test actual application against SQL Server 2008 Test setup of application against SQL Server 2008 Basic optimization review (e.g. run DTA) Explore new/enhanced features with applications

Replaced by Integration Services Deprecated in SQL Server 2008 But you can still use a DTS packages as is Basic migration tool as part of setup 3 rd Party tool DTSXchange.

Identify Upgrade Requirements Agree Acceptance Criteria Complete the Upgrade Checklist Run the latest Upgrade Advisor Pre-Upgrade Considerations Determine Appropriate Upgrade Strategy Upgrade Process Post Upgrade Considerations

Document existing solution Capture performance baseline data Develop criteria and unit / verification tests Optional: capture query plans for complex queries Ensure Clean Environment Backup old instance / database and Verify it! Loop in Windows Administrators, SAN Administrators and Network Operations Optional: Access to Support

Document EVERY step to the last detail and follow the document Check database consistency Monitor upgrade progress Check timing and compare to test upgrade timing

Review all logs Change the compatibility level Change the page verify option Revisit Upgrade Advisor recommendations Update statistics to ensure performance Reconfigure Log Shipping Re-populate Full-Text catalogs Verify Agent jobs and maintenance tasks Verify security settings, especially cross server and/or cross-domain access privileges

Re-evaluate statistics Check Optimizer Hints Database Tuning Advisor Leverage New ‘Low Cost’ Features Backup compression Transparent Data Encryption Make use of schemas Plan DTS Migration

The smallest detail missed can break the entire upgrade A tested rollback plan is critical Don’t jump to conclusions if performance issues are encountered There are lots of resources to help you and your partners/customers…
