At gigabit speeds, you're looking at over a week of transfer time: 1
gigabit = 125MB/sec = 800,000 seconds = 9.25 days, not counting protocol
overhead.  You could speed this up with link bonding, which from
previous threads sounds like something you're working on already.

If it's a oneoff transfer and you can afford downtime while you're
fiddling with hardware, you may consider directly attaching both sets of
storage to the same machine and doing a local copy.
