Portal upgrade from EP6 to EP7
We have SAP EP version 6 and planning to upgrade it to EP 7. We are using Biller direct ver 3.0 and XI ver 3 as well.
I would like to know whether there are any significant issues in this upgrade that we should be aware of. Specially any dependencies of R3 system requirements, Biller Direct and XI .
I would like to here from people who have already have experience of doing this upgrade in their EP environment.
Also would like to know the stability of EP7 compare to EP6 .
