## Procedures

- `GetDisplayName(): Text[250]`
- `GetDescription(): Text`: Gets a description for the migration type. This value is shown in the wizard.
- `GetAppId(): Guid`: Gets the ID of the app that defines the implementation.
- `SetupReplicationTableMappings()`: Sets up the replication table mappings. These mappings are used to move the data during the replication phase. This is the default way to move the data.
- `SetupMigrationSetupTableMappings()`: Sets up the migration setup table mappings. These mappings are used to replicate the data during the setup to SaaS, so the on-premise data can be used to configure the migration. It is recommended to move a small subset of the tables that do not contain large amounts of data, otherwise the setup wil...

## Ask your agent

Procedure bodies are not stored here (D10). For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "interface", object_name: "Custom Migration Provider")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
