The license can easily migrated to a new account. Just send us an email and we switch the license from your old account to the new one.
In principle, you can use a Paperpile account under a different Google account than the one that is used for the current Chrome profile. You just need to go to Paperpile Reference Manager and then go to https://paperpile.com/reauthorize
But we recommend not mixing Google accounts. So if your new account is your main account you are planning to use in the future, we suggest starting a new Paperpile account under this account.
We hope to finally have an automatic migration tool later this fall. At the moment it’s unfortunately not a one-click solution and you would need to export and re-import the data. See the discussion here:
