Started a webpage that now contains a lot of analytic data. Now that I have the client GA Tracking ID I would like to move the data I already have to that account.

Is this possible?

I get the Google Analytics API, I can always fetch all the data I want, but my problem is, upon I have the data how can I send / push this data to other account

in other words, How can I transfer data?

The domain is the same, only the account Id in use was a different one (my own, instead of the client's)

import google-analytics export data-transfer
