Provides access to members that migrate a dataset.
Description
The IDatasetMigration interface has methods for migrating the geometry, attribute and raster binary storage types of a dataset from an SDE data source. The migration path is based on parameters of the specified keyword.
Members
| Name | Description | |
|---|---|---|
 |
MigrateAttributeStorage | Migrate the attribute field storage. |
|
MigrateGeometryStorage | Migrate the geometry field storage. |
|
MigrateRasterStorage | Migrate the raster storage. |
|
MigrateStorage | Migrate all binary field storage. |
IDatasetMigration.MigrateAttributeStorage Method
Migrate the attribute field storage.
Public Sub MigrateAttributeStorage ( _
ByVal ConfigurationKeyword As String _
)
public void MigrateAttributeStorage (
string ConfigurationKeyword
);
Remarks
The MigrateAttributeStorage method will migrate all attribute binary storage to the parameters specified in the ConfigurationKeyword argument.
IDatasetMigration.MigrateGeometryStorage Method
Migrate the geometry field storage.
Public Sub MigrateGeometryStorage ( _
ByVal ConfigurationKeyword As String _
)
public void MigrateGeometryStorage (
string ConfigurationKeyword
);
Remarks
The MigrateGeometryStorage method will migrate all geometry storage to the parameters specified in the ConfigurationKeyword argument.
IDatasetMigration.MigrateRasterStorage Method
Migrate the raster storage.
Public Sub MigrateRasterStorage ( _
ByVal ConfigurationKeyword As String _
)
public void MigrateRasterStorage (
string ConfigurationKeyword
);
Remarks
The MigrateRasterStorage method will migrate all raster storage to the parameters specified in the ConfigurationKeyword argument.
IDatasetMigration.MigrateStorage Method
Migrate all binary field storage.
Public Sub MigrateStorage ( _
ByVal ConfigurationKeyword As String _
)
public void MigrateStorage (
string ConfigurationKeyword
);
Remarks
The MigrateStorage method will migrate all geometry, attribute and raster binaries to the parameters specified in the ConfigurationKeyword argument.

Remarks
An exclusive schema lock should be acquired for the dataset prior to calling any of this interface's methods. An exclusive schema lock can be acquired by using the ISchemaLock interface.
The IFeatureClassStorage interface can be used with an SDE feature class to determine the type of geometry storage being used. If the geometry is migrated to a new storage type, the feature class must be re-opened for the IFeatureClassStorage to return the new value.
Consult the topic "Data migration from one storage type to another" in the ArcGIS Help system prior to migration. There are special cases to be aware of; for example, migrating from SDEBINARY to GEOGRAPHY with SQL Server is not recommended for feature classes with Z or M values.
