We might be forced to put aside 2 weeks learning a new database More like 2 days, likely less. Unless you're using MySQL specific functionality (fulltext index?) or rely on MySQL specific bugs there shouldn't be much of a transition to speak of. (I'm ofcourse assuming you have at most one MySQL host in production and not terabytes of data to re-import...)
