Clarification on support for OAuth 1
It was recently announced that Dropbox API v2 would support OAuth 2 only.
Does this mean that existing apps which use OAuth 1 will stop working when API v2 is rolled out?

Dropbox StaffAPI v1, a.k.a. the Core API, supports both OAuth 1 and OAuth 2 and will continue to do so. Note that API v1 is already deprecated in favor of API v2.
API v2 only supports OAuth 2.
The /1/oauth2/token_from_oauth1 endpoint you mentioned allows you to get an OAuth 2 access token from an OAuth 1 access token. We recommend using that while API v1 is still enabled in order to migrate your existing users to API v2.
When you do migrate your app to API v2, you should also migrate to using the OAuth 2 app authorization flow itself in place of the OAuth 1 flow.
