Exchange 2013 CU2 to CU7 upgrade

Hi,

I have an Exchange 2013 Server standard edition, its a multi role server (standalone) with no other Exchange 2013 servers.

I need to upgrade this Server from Exchange 2013 CU2 to Exchange CU7.....most from what I have been reading is that I can upgrade directly, but there was one article I read that recommended I upgrade to CU4 first and then CU7.

What is the general consensus on this? Go from CU2 to CU7 or from CU2>>>CU4>>>CU7?

Thanks

S
