Upgrade EP from 7.0 to 7.31?

Hi, Is there a direct upgrade path available from 7.0 to 7.31? we are looking to update our old portal, was looking at if we can update it directly from 7.0 to 7.31?

Or, do we have to go thru the option of updating 7.0 to 7.3 first, and then install the EHP1 to bring up the system to 7.31

Any inputs are appreciated?

Thanks
