NW 7.3 upgrade to NW 7.3 EHP1 upgrade

Hi,

I have installed NW 7.3 portal in Linux.

I want to upgrade to ehp1. But it is under temp license.

Can I add it solman before getting the permanent license and generate support stack for portal system and upgrade it to ehp1 ?

Please suggest.

Thanks in advance.
