function hook_content_migrate_data_record_alter in Content Construction Kit (CCK) 7.3

Implement this hook to alter individual data records as they are migrated.

This hook is called after the old data record has been read from the database and before it is inserted into the corresponding D7 field. The data column names are renamed in a one-to-one mapping by the order they appear in the database. This is often the desired behavior, but in some cases an implementation of this hook may need to move data between columns.

Parameters

$record: The data record, as read by _content_migrate_batch_process_migrate_data(). If the ordering of the D6 and D7 field columns remain the same, no action is required. If the columns were re-ordered or the data format was changed, $record should be modified to fit the new field definition.

$field:
