I have been asked to install a SAP landscape with three Systems DEV, QUA, and PRD( Environment - WIndows with Mssql). All with different client numbers, i have two options either i do Fresh installation for all the three systems and then do post installation tasks, or i do a system copy of my DEV system and then build the QUA, and PRD system followed by SCCL in both the systems respectively( to change the client number). Need to know which is a better practice? and why should i perform that?, which process is time efficient and will consume less amount of time. Please let me know.
If this has already been discussed, please provide me the link,i am not able to get that.
