If shutting the machines down is feasible, I’d put the source hard drive into the destination machine and use rsync to copy it from one drive to the other (rather than using rsync to copy from one machine to the other over the network).
I'm not so sure about that. Probably the disk is the bottleneck, not the network. Assuming that one of the drives is a 7.2krpm drive it will have a sequential read / write performance of somewhere around 120MB/s although newer spinning drives do seem a tad faster than that. Running uncompressed Rsync over SSH over a Gbit network I have seen more than 100MB/s however if your files are compressible then you can see much better performance.
If your ethernet network is 100Mbit/s or the source and destination networks are both SSD then yea... what he said :)
