Fix Your Tools: Fix Your Tools Migrate DTS Packages To SSIS 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: 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.
Fix Your Tools: Fix Your Tools Migrate DTS Packages To SSIS Packages not upgraded will need to be redeveloped in SSIS.
Fix Your Tools: Fix Your Tools Migrate DTS Packages To 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.
Fix Your Tools: Fix Your Tools Migrate DTS Packages To SSIS 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.
