Exchange 2010 move from one Exchange Organization to another

Hello Experts.  We have two offices and currently running two different Exchange Organizations.  I want to just have one MS Exchange Organization but not sure how to proceed.  I am running exchange 2010 on windows server 2008 r2

In the end I want one Exchange Organization that covers both offices.  My question is.  What is the best way to get the mail databases from one organization to another?   There are only 7 mail users in the branch office so there is no issue in creating them again, my issue is the email itself.

Thank you

Thank you.  I can try that but since there are only 7 users. Couldn't I just create all new accounts for them, then import the Pst?
