How to switch around two linked Gmail accounts?

Question

I have two Gmail accounts:

• The embarrassing one I set up as a teenager, let's call it woohoo9000@gmail.com
• The serious one I set up as a young adult for job applications etc, let's call it my.name@gmail.com

When I first set these up, I linked them so that I'd only have to check one inbox to see all my emails. Because at the time, I was used to using woohoo9000@gmail.com, had used it for site logins, etc., and it was what my friends, family and other accounts used, I set that up as the account I'd be logged into:

• I added my.name@gmail.com as a new "Send mail as" account in woohoo9000@gmail.com's settings then set it as the default
• I used "Grant access to your account" to allow woohoo9000@gmail.com to access my.name@gmail.com's messages and set my.name@gmail.com to forward incoming mail to woohoo9000@gmail.com's inbox and

So, I can be logged in on my browsers and android devices to all those Google accounts - such as Google Drive, Android, Google Play, and Google logins on sites like SE - that are part of the woohoo9000@gmail.com Google account, and that account's Gmail is set to send and receive emails via the newer, more respectable my.name@gmail.com name.

I thought this worked fine - but then it turned out to be a big mistake. To my horror, I saw things like this creeping in to serious email conversations, even though the sending email account was set to be my.name@gmail.com:

From: woohoo9000@gmail.com On Behalf Of my.name@gmail.com

Sent: 25 February 2016 10:55

To: manager@seriousbank.com

Subject: Serious financial matters

Not a great first impression.

How can I switch the priority of two previously linked Gmail accounts, so that my.name@gmail.com is the primary account and no mention of woohoo9000@gmail.com can creep in unless I manually send from that account - but I can continue to be logged in to all the peripheral stuff linked to my original woohoo9000@gmail.com Google account?

I've seen lots of guides on how to do the initial linking of the accounts, but not how to switch the linking around once it's done.

I couldn't find any clean way of doing this so I've settled for simply having the old account forward to the new account, then, logging in to both everywhere, with the old account as the default Google account on my devices and the new Gmail account as second Google account I use for and email only.

Took a bit of work and isn't entirely straightforward or convenenient, but it works in as far as it removes the embarrasing email address from my outgoing mail while still letting me use my other Google account features and check only one inbox:

• First, doing it this way, you need to log out of your Google accounts and log back into them in this order, and do it in this order each time when using a new desktop/browser:
  1. Log into the old Google account first, so that it's the "default account" for all those other Google services
  2. Then log into the newer Gmail account, using "Add account" from clicking on the round avatar thing in the gmail.com top right hand corner, so it's logged in to both with this as a secondary "additional account"
• There doesn't appear to be a clean way to have Gmail in a browser treat a non-primary Google account as the default inbox, so I'm resorting to simply bookmarking the Gmail page for the other inbox, https://mail.google.com/mail/u/1/#inbox (/1/ not /0/ means inbox for the second logged in account), and remembering to go to that bookmark instead of just Gmail.com which will redirect to the first account
  • Or better still, manually create a bookmark for https://mail.google.com/mail/?authuser=your.name@gmail.com which will automatically redirect to that inbox regardless of which order you logged in to what. Credit to Aʟ ᴇ's post here
• In the Gmail app on my Android devices, I've added the newer email address and - since I've set the old one to forward to the new one - turned off notifications and syncing for that older account's Gmail settings only (since signing out would sign out of all the other Google services)
• Then, to see any emails sent to the old account in the new account's inbox, it's a matter of having the old account forward emails to the new one instead of visa versa using its settings from Gmail in a browser. I'm using forwarding because for some reason Gmail's "Check email from other accounts" feature isn't working for my accounts, which appears to be a common problem looking at the Google messageboards.
