Start out by adding or reserving one browser to log in only to your old account. I used Opera
- Google maps settings: Google Takeout but useless because you can't upload it
- 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.
- 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
- 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/
