Nuby migration question -- data migration, MySQL => postgres

How do I best migrate the data? For small databases I can text-edit the
dump file from
MySQL. The postgresql compatibility switch doesn’t help on mysqldump.
Any ideas. Can
MySQL export CSV that postgresql can import ?

Yes, PostgreSQL can import a CSV. :slight_smile:

I’ve also worked on a rake task in the past that would talk to a
MySQL db (Rails app) and then after I generate the PostgreSQL db with
the same schema (with the different field types)… I would just run
rake mysql2pgsql and it’d go through a yaml → model → save process.
It worked pretty well on a few projects.

Email me off list and I’ll see what I can dig up this week for you.
