Step 1 – Assess Your Readiness
• Swim Suit Still Fit?– Time to upgrade hardware?
• Sun Screen Out of Date?– Inventory User Accounts,
Databases & Delete Unneeded
• Make a To Do List– Run SQL Server Upgrade
Advisor
Step 1 – Assess Your Readiness
• DNREC Hardware– Pre-Upgrade
• 2 quad Processor Servers in Active/Passive Configuration with 1 TB SAN
– Post Upgrade• 2 Dual Core Hyper-threaded 64
bit Quad Processor Servers in Active/Passive Configuration with 3 TB SAN

• There are problems directly migrating DTS packages from the server to SSIS
• Online resources indicate problems lie in Package names.
• Upgrade advisor does not check this.
• We chose to export from 2K5 to Structured Text Files then upgraded each separately.

Fix Your Tools
• Migrate DTS Packages To SSIS
• Upgrade wizard will not convert all tasks.
• Tasks not converted will remain DTS tasks within a SSIS rapper.
• This causes confusion with connection strings as they are changed in the DTS package, not the SSIS rapper.

• Packages not upgraded will need to be redeveloped in SSIS.

• SSIS Development– Be careful of the 64 bit environment– SSIS will not use 32 bit drivers event
if installed on the server.– This has implications when
accessing data with Jet drivers as no 64 bit versions do not exist.
– Explicit data type conversions are expected especially between Unicode and non-Unicode.

• SSIS development environment validates on the fly.– While this is a nice feature it can take
some time when validating large packages.
• SSIS will not retain passwords within the connection strings.– Workaround is to use configuration
files.
