4. Agenda Definitions What can be upgraded How to upgrade Upgrade Plan Pre-upgrade Upgrade Execution Post-upgrade In-place Upgrade vs. Migration Upgrading Log Shipping Upgrade Tips and Best Practices

5. Definitions Upgrade (or in-place upgrade): – Updates an existing installation while preserving user data – Instance name remains the same after upgrade – Automated process Migration (or side-by-side migration): – Starts with a new installation – New & old instance reside side-by-side – Objects are copied from the old to new instance – Mostly a manual process

6. In-place Upgrade SQL Server 7.0/2000 Instance: Foo SQL Server 2005 Instance: Foo Upgrade

7. Compare and Verify SQL Server 7.0/2000 Instance: Foo SQL Server 2005 Instance: Bar Side-by-side Migration Verified!

8. What can be upgraded or migrated? Versions – SQL Server 7.0 (latest service pack) – SQL Server 2000 (latest service pack) Components – Database Engine – Includes sub-components like SQL Agent, Full-text, Tools, etc. – Analysis Services – Reporting Services – Notification Services – Migration of Data Transformation Services to Integration Services Editions – Desktop, Workgroup, Personal, Standard, Developer, Enterprise Platforms – 32-bit & 64-bit (IA64 and x64) Languages – All SQL Server 7.0 and SQL Server 2000 released languages

9. Upgrade Plan Smooth upgrade requires a good plan Devise an upgrade plan by grouping upgrade tasks into: 1. Pre-upgrade tasks 2. Upgrade execution tasks 3. Post-upgrade tasks – 0 day, 30 day, 90+ day Exercise upgrade plan

10. Pre-upgrade: Prepare Your Environment Study SQL Server 2005 minimum hardware & software requirements Get an inventory of your applications & legacy systems – Releases, Components, SKU’s, Platforms Opt for the same or a compatible edition – Check features in each SQL Server 2005 SKU – Beware of cross-SKU upgrade matrix Record benchmarks – Functional, Performance, Stress Run Upgrade Advisor Examine issues reported by Upgrade Advisor Fix or work around backward compatibility issues

11. Pre-upgrade: Backward Compatibility Some features are discontinued: – They do not appear in SQL Server 2005 – Example: Undocumented system stored procedures, Virtual cube, Virtual dimension… Some are being deprecated: – They won’t be supported in the release following SQL Server 2005 – Example: SQL Mail, Calculated Cell, Cell evaluation list… Some features have a different behavior – Example: Database Engine catalog security Some editions have a different feature set – Example: Express does not have SQL Server Agent Check Books Online for a full list as well as replacements and techniques Run Upgrade Advisor before any migration or upgrade

12. Pre-upgrade: Upgrade Advisor Tool Improves the SQL Server 2005 upgrade experience Avoids surprises during or after upgrade Analyzes SQL Server 2000 and SQL 7.0 instances Analyzes objects on server; script and trace files Performs read-only operation Provides a report for detected issues Presents guidance on when detected issues need to be fixed Describes how to fix or work around issues Has links to documentation for additional content Download from web http://www.microsoft.com/downloads/details.aspx?FamilyID=cf28daf9-182e-4ac2-8e88- f2e936558bf2&DisplayLang=en http://www.microsoft.com/downloads/details.aspx?FamilyID=cf28daf9-182e-4ac2-8e88- f2e936558bf2&DisplayLang=en

13. Pre-upgrade Upgrade Advisor Report Upgrade Post-Upgrade Ready for upgrade Upgrade Advisor

15. Upgrade Execution Choose an in-place upgrade or migration strategy for each component Understand upgrade and migration tools for each component Check databases consistency Back up old instance – Verify backup Monitor upgrade progress via setup log Be prepared to execute your back out plan

16. Pros & Cons of Migration Pros – Migration provides more granular control over the upgrade process – Having new and old instances side-by-side helps with testing & verification – Legacy instance remains online during migration – Flexibility to implement migration with failover Cons – May require new or additional hardware resources – Applications need to be directed to new instance

17. Pros & Cons of Upgrade Pros – Easier, faster, less headache for small systems – Requires no additional hardware – Applications remain pointing to old instance Cons – Less granular control over upgrade process – Instance remains offline during part of upgrade – Not best practice for all components – Analysis Services cubes are recommended to be migrated

18. Upgrade & Migration Tools Setup is in-place upgrade tool – Database Engine – Analysis Services – Reporting Services Wizards for side-by-side migration – Analysis Services – DTS to Integration Services Specific configuration tools for migration – Reporting Services – Notification Services Upgrade Advisor is upgrade analysis tool for all components

19. Upgrading Database Engine Setup.exe performs the in-place upgrade Several migration techniques for Database Engine: – Detach/Attach – Backup/Restore – Copy Database Wizard, DTS – Manual scripts, BCP

20. Upgrading Analysis Services Choose one of the upgrade techniques 1. Setup.exe for in-place upgrade 2. Migration 3. Migration ++ Install a new instance Import as project Add new SQL Server 2005 features 4. Redesign from scratch

21. Upgrading Reporting Services Reporting Services 2005 supports both upgrade and migration from Reporting Services 2000 Migration tool – Reporting Services Configuration tool Upgrade will work unless server is not configured with default configuration

22. Data Transformation Services DTS Packages will continue to run alongside with SQL Server 2005 Integration Services (SSIS) SSIS is not the next version of DTS – SSIS is first version of a whole new product Packages can be migrated to SSIS via DTS Migration Wizard Migration wizard copies DTS packages and then re-creates them in SSIS – Migration is not perfect – it’s a “Best Effort” migration – Redesign is a better option!

23. Upgrading Replication Publisher Subscriber Distributor Subscriber Distributor can be any version as long as it is greater than or equal to the Publisher version Publisher can be any version as long as it less than or equal to the Distributor version Read-only Subscriber to a transactional publication can be any version within two versions of the Publisher version Updatable Subscriber to a SQL Server 2005 transactional publication can be any version equal to or greater than SQL Server 2000 SP3 Subscriber to a merge publication can be any version less than or equal to the Publisher version Distributor

24. Upgrading Legacy SQL Server Tools SQL Server Agent has a new security model (proxy account) Registered Servers can be upgraded to Management Studio Database Diagram are upgraded into the new SQL Server 2005 format Database maintenance plans can be migrates to new Maintenance Plan packages
