Hi,
We have our ECC system on NW 7.0 EhP3 and our HR portal on NW 7.0. Can we upgrade only the HR portal to NW 7.01 leaving the ECC backend to NW 7.0? Upgrading the ECC backend to EhP4 is in the pipeline, but due to some reasons it has to be postponed by few months. Can we proceed with upgrading the HR portal for now and later the ECC landscape? Will there be any inconsistency due to this?
