// IMPORTANT NOTE: this migration was written when we were using version 3 of lodash.

// We've now upgraded to lodash v4 but the code used in this migration has not been
|
|
// adapted to work with it. Before this migration is used again any lodash method should
|
|
// be checked for compatibility against the v4 changelog and changed if necessary.
