If you do not know the completed process Start to End for doing an upgrade. I would highly recommend using the Exchange Server Deployment Assistant. This will provide you with all of the high level steps that are required. It will also assist if you want to have a hybrid solution using Office 365.

Exchange Server Deployment Assistant

Really too much to go over in one post, but the high-level process would look like this:

1. Use the role requirements calculator to assign the appropriate amount of resources to your servers - https://gallery.technet.microsoft.com/office/Exchange-2013-Server-Role-f8a61780

2. Test functionality using the JetStress tool - https://www.microsoft.com/en-us/download/details.aspx?id=36849

3. Install all prerequisites and hotfixes - https://technet.microsoft.com/en-us/library/bb691354%28v=exchg.160%29.aspx

4. Install Exchange, create DBs, and configure DAG

5. Install SSL certificate and verify functionality with Outlook/OWA/ActiveSync

6. Verify internal/external mailflow

7. Configure client access load balancing (optional)

8. Once all functionality is verified, schedule a maintenance window for migration and move 2010 mailboxes to 2013 DB(s).  This is assuming you can move all mailboxes in one window, otherwise co-existence will be required and you'll want to plan accordingly - http://blogs.technet.com/b/exchange/archive/2014/03/12/client-connectivity-in-an-exchange-2013-coexistence-environment.aspx
