We are planning to upgrade our SAP Portal which is on NW 7.0 EHP2 to NW 7.4 . Our backend is ERP6.0 EHP6. We are using portal for ESS/MSS package and SSO to SAP.
Need some information on this area.
1. Can we directly upgrade Portal to NW7.4 without any need to upgrade our backend system component.
2. Does TREX also need to be upgraded when upgrading portal .
Can some one share a step by step guide on how to upgrade portal on things . Yes i have am going through upgrade guide but someone who has done it before and capture steps will be helpful as i have not done portal upgrade before
Thanks
