upgrade question - from Dorico 2 to Dorico 3

Hi, sorry to ask an obvious question, but I can’t find the answer and have a very slow internet connection, so want to check first:
To update Dorico 2 to Dorico 3, do I need to download the Sounds Installer, or are they already all in Dorico 2?

There are some extras such as the Olympus Choir that come with the Dorico 3 sounds installer. To the best of my knowledge there’s no way or downloading just the additions; it’s all or nothing.

Welcome to the forum, HopefulBear. Leo’s quite right: you should really download the sounds for Dorico 3, but the only thing you’ll be missing if you don’t is the Olympus Choir Micro vocal sounds.
