Upgrade from ERP EHP5 to EHP6, impact in landscape ?
We are thinking to upgrade from ERP EHP5 to EHP6 and I concerned about impact in the landscape.
Basic reasons to upgrade are implementation of ESS and MSS and the oportunity to use new functionality via Business Function available in EHP6 form HCM module.
Our actual landscape is
ERP EHP5 SP4
SRM EHP1 SP4
NW Portal 7.02
NW PI 7.3
NW BI 7.02
Solman 7.0 EHP1
If we upgrade ERP to EHP6, my questions are:
We need to upgrade Portal to 7.3 to use full functionality of ESS and MSS ?
If yes, how impact in SRM 7.01 ? Need to upgrade SRM too ?
Integration guides recommend to align landscapes with stacks
SRM 7.01 - ERP EHP5 - EP 7.01 - PI 7.01 or
SRM 7.02 - ERP EHP6 - EP 7.3 - PI 7.3
but, at the moment, we prefer avoid upgrades if its possible (our installation is young ...)
Thanks in advance.
