Have you read part 1/2?

Avoid confusion (options):

Because you’re going to be using both accounts for a while, it would be a good idea to keep your data in one place, and not in both. Once you have verified that your calendar data and contacts are both in your new account, It would be a good idea to delete all that information from your old account.

To delete your calendar data:

  • Go to your Calendar
  • Click on “Calendar Settings
  • Click on “Calendars” tab
  • Click on “Delete

You will receive a warning. Just confirm, and your calendar data will be deleted. Repeat this process for any additional calendars.

To delete your contact data:

  • Go to your Contacts
  • Click on the check box on the top of your contacts , so that all your contacts are selected
  • From the “More Actions” drop down, select “Delete…”
Setup your mail redirection:
Because we want to avoid having to move all sorts of mail, we will just setup a redirect to all mail from the old address to the new one. This will be transparent to both you, and the people who are sending you emails. At the last step, will be setting up a method to finally nicely force people to record your new address.
To setup the forwarding:
  • Go to your old account settings
  • Go to the “Forwarding and POP/IMAP” tab
  • Select  “Add Forward Address
  • Type in the new email address.
    (at this point, you will have to go to your new mailbox, and verify that address)
  • Once you save  that page, you will see 2 new options: Disable Forwarding, and Forward a copy of incoming mail to.
  • At this point, the first drop down should contain your new email address. So, select that line to read:
    Forward a copy of incoming mail to newaccount@gmail.com and delete Gmail’s copy

What this will do is take all incoming mail, and send it over to your new address. Transparently to you.
Because this is so transparent, you may want to set up a filter in your new account to differentiate between messages that were sent to your new address vs your old address. This trick will be useful to pin point any accounts websites / accounts / credit cards, etc , which still have your old email address, and will prompt you to go and change those at a later time. Meanwhile, no email flow will be interrupted, or inconvenienced.
To setup the filter, in your newaccount@gmail.com, go to your Mail Settings

  • Click on Create New Filter
  • In the “To” box, type in your old email address: oldaccount@gmail.com
  • Click next
  • Check the “Apply Label“, and select “New Label” from the drop down, and name it “Old Account”

Create new Filter

Create a new label and call it: Old Account

Now, any mail that was sent to the old account will end up in your new mailbox, but will be tagged with a label.

Setup send on behalf of, on your new account:

In order to avoid having to keep going back and forth between your accounts, setup a “Send mail as” your old account, on your new account.

To do this:

  • Go to Mail Settings
  • Under “Send Mail As“, click on “Send mail from another address
  • In the “Email address” field, type in your oldaccount@gmail.com address, and click “Next Step
  • Then click on “end Verification
  • Go back to your old account, and check your mail. You have a 5 or 6 digit code. Type that in, and click verify

Type address

Type in the address you want to send as. In this case, oldaccount@gmail.com

Send verification

Send verification, then check your old account email

Enter verification code

Enter the verification code that your received in your email

Now that you’re all basically setup, it would be a good time to send out an email to all your contacts informing them of the new email address. You can send it from your new, or old address.
Send message as old email

Since you already sent out the main message, and since you can’t be sure that everyone is going to change their address-books immediately, you want to have a backup plan, so that you make sure everyone eventually has your new address. For this reason, you can setup an “Vacation Auto Responder” on your oldaccount@gmail.com, which informs your contacts that this email is no longer checked, and inform them of the new email address. For the lazy people, they’ll eventually get tired of the auto-responder, and will change their address-books. Even though the message will say that the email isn’t checked anymore, this is only informative to your users, as all email is already automatically being forwarded to your new address.

Step 3: Miscellaneous items.
There are a couple of items left for the migration.

Google Voice

If you have a Google Voice account that you would like to move over to the new address, there is a form that you would have to go through to submit that request. Google will take up to 5 business to process. If you already have a Google voice account on the new account, and you apply for the transfer, the old information will replace your new one, and this process is irreversible. Google will warn you plenty of times before submitting the request.

go to the Google Voice migration submittal form

iPhone or Mobile Device

Since all mail and calendars are likely being synced to your mobile device, you want to make sure to change all the account pointers on your phone, to point to the new account.
In brief, the quickest way to do this, is to just change the username on your iPhone’s mail setup from oldaccount to new account, and change the label of your account to “New Gmail” or something recognizable.
In addition, add a new IMAP connection on your phone, pointing to your old gmail, so that you still have access to your old archived messages as well, without having to login and logout multiple times. Make sure you turn off your Calendar, and Contact sync on the old account, and keep them on, on the new account.
One last step is to re-sync your calendars with the new gmail account:
To do this


  • log out of any google accounts you have on your phone, and re-login with the new one.
  • open Safari, and navigate to: http://m.google.com/sync
  • Select your iPhone device, and then check all the calendars that you would like synced with your phone
    You will be able to choose up to 25 calendars, including shared calendars


Remember, if you had any shared calendars, or were sharing calendars with other people, you will need to re-share those as well.
