SRM Enterprise Portal

Hi Experts,

We are going to perform SRM Upgrade from 5.0 to SRM 7 Ehp3, where we are using ITS portal used by endusers. Hence we learnt that in SRM7 Ehp3 Netweaver Enterprise Portal is a must and we are migrating the ITS portal to ABAP Webdynpro and accessed via Enterprise Portal for end-users.

Please clarify the below:

We have SAP BI Portal 7.31 and MDM7.0, can we use this as SRM Portal too after deploying the relevant SRM7ehp3 java components in any of these Portals?, will there be any conflicts if we do this?

or We need to have a separate portal for SRM7?

Thanks!!
