Several table were scanned via White Rabbit which output was used as input into Rabbit In a Hat. Mapping was done on several tables and saved to a master mapping file. Several additional tables were scan via White Rabbit and need to incorporate this information into the master mapping file. It is not evident on how to combine the two White Rabbit outputs. Is this possible?
The goal is to have one mapping file which can be updated with database tables changes and then use Rabbit in a Hat to map the changes.
