Hi, Martim,
i could not say something to V7R2, we are on V7R1.
but
the point is, that a SAP homogeneous system copy is not a 1:1 copy,
because SAP is delivering newer components and new default-values in profile-parms within SWPM, such as new Kernel a.s.o.
have a look at this issues:
SAP changed default-values in profil parameter, is a change log available?
