Got a Google+ Personal Account?
For those of you that may have setup your Google Plus account with your personal Google or Gmail account, Google Plus finally launched today Google+ for Google Apps accounts, but there is no merge functionality.
Should you setup two different Google+ accounts? If you are logging out of your Google Apps account to use your Google+ personal account and you like to +1 web pages, I say go for it. If you can wait a few weeks, Google says that they will have a solution.
Google+ Migration Tool Coming Soon
Google announced that for those who’ve already started using Google+ with a personal Google Account and would prefer to use your Google Apps account, Google is building a migration tool to help you move over.
No Need to Rebuild Circles
With this tool, you won’t have to rebuild your circles, and people who’ve already added you to their circles will automatically be connected to your new profile. Be patient, Google doesn’t expect this migration option to be ready for another few weeks.
Go ahead and get started with your Apps account now and merge your connections once the tool is available.
