Porting everything to a new google account

Start out by adding or reserving one browser to log in only to your old account. I used Opera

1. Google maps settings: Google Takeout but useless because you can't upload it
2. Google drive: VaultMe. It's paid but it works well. We tried going a google takeout, but the file ended up being useless to open (corrupted) and we found out that is common with large google takeout zip files.
3. Google Blogger: go into old account into each blog and send yourself an invitation, accept it from the new one, go back in the old one and elevate yourself to admin
4. Google Calendar: We tried  doing an export, but the ics file ended up being too big to then import into my new Google Calendar. But we found a free open sourc tool from github that easily split it into small chunks we could import: https://brokenvectors.github.io/
