Usage

Authorize Credentials

Follow steps in the official quickstart guide in section Authorize credentials for a desktop application. Place the downloaded credentials.json in the same directory root of migrate.py in this project.

Install Dependencies

$ pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib

Run the Program

Run python migrate.py in your shell. A browser page will be opened and you will be prompted to log into your Google account to provide Tasks access. You will need to log in to your source (from which tasks will be exported) and destination (into which tasks will be imported) accounts in order.

Once you're done with logging in to both accounts, the transfer process will commence and you will see terminal outputs similar to the following:

(googleapi) ➜ python migrate.py
