How to install portal on Netweaver 04 WebAS SP16 ?

Hello SDNers,

We need to have Enterprise Portal installed on our NetWeaver 04 WebAS Java SP 16.

The following is our setup:

1. WebAS SP09 was installed without Enterprise Portal SP09.

2. Patch upgrade applied on WebAS from SP09 to SP16.

Now is it possible to install Enterprise Portal SP09 on this WebAS SP16 single instance ?

Can we then apply patch upgrade to EP from SP09 to SP16 ?

Any help on this would be appreciated.

Thanks and Regards

Uday
