Data Migration

• CSV (beware DB locks!)

  python web2py.py -S prod -M
  db.export_to_csv_file(open('db.csv','wb'))
  Ctrl+D
  

  Remove reference Tables from CSV file (don't want to import duplicates!)

  python web2py.py -S dev -M
  db.import_from_csv_file(open('db.csv','rb'))
  db.commit()
  Ctrl+D
  

• Web services (better to avoid locks)
  • Currently needs to be done resource by resource (JOINed tables can be done together as Components of main resource)
    • need to do referenced tables before the tables which refer to them
    • migrate the locations first (using the xml interface), you can later migrate the orgs and offices together (through Component JOIN)
  • Ideally we want to develop a way of having all tables loaded together into RAM, refs fixed-up & then imported to db together
