Upgradation from 4.6c to ECC 6.0
My client has already implemented ESS and MSS(MDT) in 4.6c,now they want to updgrade to ECC 6.0.
If all the configurations including the customized are moved to ECC6.0 will they work in ECC 6.0 ? (Both for ESS&MSS) or do we need to reconfigure all?
I need some help in this regard
