How to transfer all important data from one Google account to another?

Question

Google

In general, I have had a Google account since ancient times. On the one hand, it has all the necessary information (purchased applications, calendar, Hangouts, disk), on the other hand, I have polluted it with so many junk mailings that life is not enough to unsubscribe (they usually use the left address for such things, and I foolishly , and now out of habit, gave it). In general, there is another account - the developer. I would like to somehow transfer all the necessary data to it, and not to transfer unnecessary ones. Is this even possible?

Answer 1

Google takeout to create a full backup. Disk data, google plus photos is easy to pull out. Create a new account. Download all data to disk. Bookmarks, contacts and calendar are unloaded by standard means. Purchased software is non-transferrable. You can transfer the mail archive. Labels also.

Answer 2

Have you tried turning off mail?
