Change Primary Google Account? Save apps? Save data?

[jeremyhays]

I have a Samsung Galaxy S4. I set up the phone using my work-associated Google apps account. That account has been my main Google account. After several months, I added my personal Google account to the phone so I could check email in the Gmail app, see my personal calendar, etc.

Now I want to complete remove the primary Google apps account from my Android phone. I want to make my personal account the primary account for this phone.

Is there any way to do that without losing all the apps I downloaded from Google Play? I don't want to do a factory reset. Thanks for any help.
