Using Marshal.dump on the French production database raised an error:
Encoding::UndefinedConversionError: "\xC3" from ASCII-8BIT to UTF-8
Replacing Marshal with YAML solves the problem. It is also more reliable
and human readable.
This code was run against the French, Australian and UK production
data successfully.

# When we introduced the Customer model, we didn't associate any existing
|
|
# customers with users that have the same email address.
|
|
# Later we decided to create that association when users sign up. But we didn't
|
|
# update all the existing customers. We do that now for data consistency and to
|
|
# solve several bugs.
