Example Shift YAML File

gistfile1.yml

from:
  adapter:
  database:
  port: 
  username:
  password:
  host:

to:
  adapter:
  database:
  port: 
  username:
  password:
  host:

mapping:
  - {"column", "column2"}
  - {"column", "column2"}
  

Oh right. I thought for a moment you'd be creating a new table.
