I guess it depends on scale? I was surprised how easy it was on Ubuntu. There was an automatic migration script, and it worked. Took less than 5 minutes to upgrade.
Sure, there was downtime, but I think most applications out there can live with scheduled downtime of a few minutes.
If you can't have downtime, then nothing is easy.

Your development environment doesn't represent production. If the distinction even exists! A five minute upgrade can become indefinite with a single lock [row/table, depending on the storage engine/etc]
