Migrating authtokens from v1 API to new access_tokens (API v2)

Migrating authtokens from v1 API to new access_tokens (API v2)

Hi,
I'm  doing migration to the new API v2. I have a question concerning new OAuth flow. Do you plan to offer some kind of migration mechanism to move existing authtokens to the new OAuth flow authorization?

I understand that this could be a problematic as with new flow user accepts the access permissions scope and such migration could require an assumption for permission level to be equal with the old authtoken scope. From the other side it could be nice feature to migarte existing API authenications from API V1 into API V2 without asking users to reauthenticate.

How do you see such thing?
