Made some testing.

Copy 500MB from one server to other. It took 20seconds. There is 1Gbps network, about 25% utilization while copying. -> 90 GB can be tranferred in one hour.
In our environment disks are limiting speed. RAID-10 system. This very system is Windows platform.

You could also try transportable tablespaces. What is your data amount? How much time to make switch? We just got our consolited server upgrade done into new server (9iR2->10R2) First week in production now, quite silent at this summer time thought.

(Well, Still an other consolidated server with 9iR2 in Linux platform, former it was in Sun Solaris/Oracle9i)
