hardware migration

dear all,

i am actually looking at migrating our production server into another server. ie from IBM 32 bit to HP 64 bit. with same OS,DB,SAP version(ECC 6.0). its just upgradation of hardware capacity. i have good idea of how database refresh is done, but i am not sure if the same procedure can be followed here as well. hope you can list me the points that i need to do extra in this case. also please suggest me the best method to follow. the OS is windows 2003, DB is oracle 10g. any links given will be highly appreciated and rewarded suitably.

thank you very much.
