Agree with Matt.
@ Nilutpal, Either you consider backup/restore or system copy, both do the same. However, I feel homogeneous system copy is easier than the backup/ restore method (considering the fact that you are going with same OS and DB vendors).
Note that, for homogeneous system copy you'll need a downtime of your source system to take export.
Hope your queries are clarified.
