Has anybody ever transfered a Kanboard installation from MySQL to PostgreSQL?

I have a longtime Kanboard installation running on a MySQL database. Since PostgreSQL is (now?) the recommended database backend for Kanboard and I have a good experience and performance of using PostgreSQL for my playground Kanboard I was thinking about migrating my real Kanboard installation from MySQL to PostgreSQL.

There are tools and concepts for this kind of migration (pgloader, fdw) but I would like to know if someone has ever tried and successfully managed something like this.
