Use BOX token from v1 to v2 API to get new tokens

Question

Is there a way to use the old access_token saved somewhere from version 1 and use it to get new tokens in the version 2 API? We know that access_token on v1 takes forever and is limited in v2.

I'm asking if this is possible because we have a bunch of users and we don't want to make them have an access to the app again. All of them will not want to do this again.

In short I want a silent upgrade and don't want to bother them by saying, "You have to grant the app again in order to get a new access".

I hope you guys understand me. Hope someone will sort this out. If it's not possible, any recommendations?

Thanks in advance.

Currently there is no silent upgrade path for access tokens. Your users must reauthorize your application. :\
