Prerequisites for SharePoint 2013 upgrade

Hi

We are running an on premise SharePoint Server 2010 farm. Our SharePoint farm is currently patched to the following version: 14.0.6126.5000 - or SharePoint Foundation Server Service Pack 1 with August 2012 Cumulative Update. 

We are wanting to upgrade to SharePoint 2013 and would like to know whether we need to patch our current SharePoint farm prior to an upgrade, or if we can upgrade from our current version?

Thanks
