Osservazioni

There are some limitations when transferring a database to a server instance that is running SQL Server 2000: 

  • If the database has a schema for which there is no corresponding user on the target SQL Server 2000 server instance, it cannot be transferred. In this case, you have to create a user who has a name that is the same as the name of the schema.

  • Any object that uses the following data types cannot be transferred:

    • SqlDataType.Xml

    • SqlDataType.VarCharMax

    • SqlDataType.NVarCharMax

    • SqlDataType.VarBinaryMax

The following object types cannot be transferred:

  • All broker objects

  • All mail objects

  • Endpoint

  • ServerDdlTrigger

  • ExtendedStoredProcedure

  • FullTextCatalog

  • UserDefinedMessage

  • ApplicationRole

To get and set Transfer object properties, users can be a member of the public fixed server role.

To transfer data, users can be a member of the public fixed server role.
