Migrating Passwords
SQL Server 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 do not retain passwords, although you must provide the password during the migration process. For information about package protection levels in SQL Server, see Migrating Data Transformation Services Packages.
注意
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 data transformation solutions. SQL Server 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.
Adding Security Features to Packages
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 DTS Package.
Digitally sign the package and set properties to ensure that the signature is checked when the package is loaded. For more information, see Signing Packages with Certificates.
Encrypt checkpoints on packages that use checkpoints. For more information, see Using Checkpoints in Packages.
