Upgrade from ECC 6.0 with no EHP to EHP 7

Hello,

We are planning an ERP upgrade from ECC 6.0, which has no enhancement package, to EHP 7.

Can this upgrade be done :

1. Directly to EHP7

OR

2. Do we need to first upgrade to a lower EHP, for example - to EHP 5 or 6 first, and then to EHP 7?

Thanks and Regards,

Reena
