The promised Django Land; the tale of one team’s epic journey from the country of Flask to Django La 

Speaker: Nicole Zuckerman
Your product doesn't stop while you take the time to do a massive rewrite in
order to change your language or framework. It seems everyone has an
opinion on what the 'best' tools are, and views changing tools as a red
flag. Many organizations do change frameworks or languages mid-stream, to
greater or lesser success; in this talk, you'll get a real-life fairy tale
of one company's move from Flask to Django, why each was the best choice at
the time, how they got team buy-in, what technical decisions made things
easier or harder, and how they switched without stopping all product work.
