I am in the process of migrating a request tracker 3.6 instance from one server to another. The old server uses PostgreSQL and the new one will use MySQL. Is there a way to migrate the data from one database to another?
After some more searching and getting the terms correct I came across the following: http://rt.bestpractical.com/view/PgToMySQL and linked from there is a Perl script that will do the required migration. It will need DBI and the mysql & postgresql drivers but seems to work pretty well.
