SQL Server 2005 only uses passwords on packages in connection with certain package protection level options. Therefore, password-protected packages that are fully migrated from SQL Server 2000 to SQL Server 2005 do not retain passwords, although you must provide the password during the migration process. For information about package protection levels in SQL Server 2005, see Setting the Protection Level of Packages.
|Password-protected packages cannot be migrated unless you provide their passwords.|
If the DTS run-time engine for SQL Server 2000 is installed, you can continue to run SQL Server 2000 packages. You can also include these packages in SQL Server 2005 data transformation solutions. SQL Server 2005 continues to support package passwords in this scenario. For example, the Execute DTS 2000 Package task includes a password property for passing a password to a SQL Server 2000 package.
After a package is migrated, you can add the following security features:
Set the protection level on the package to encrypt all or only sensitive property values when the package is saved. For more information, see Integration Services Packages.
Digitally sign the package and set properties to ensure that the signature is checked when the package is loaded. For more information, see How to: Sign a Package Using a Digital Signature.
Encrypt checkpoints on packages that use checkpoints. For more information, see Using Checkpoints in Packages.
