SAP_BASIS 702 update question

Hi. We have to install an add-ons for EWMS that are dependent on SAP_BASIS 702 version (BP-SOLBLD 70V9 and BP-CANW 702V7). Currently in our system have BASIS 701 (EHP4 FOR SAP ERP 6.0). Our doubt is: to jump to the 702 version we have to install EHP5 FOR SAP ERP 6.0 mandatorily or can only install SAP EHP2 FOR SAP NETWEAVER 7.0 without ERP? If it could, how do we build the project in the Mopz? Only allows us to realize the project for EHP5 for SAP ERP 6.0.

Thanks!
